Solara Texas Batteries: A solar installer weighing the Texas home battery market
Candidate-led market entry, the format candidates report for Bain cases: you propose where to start and walk the interviewer through your structure, and here the decision turns on one number. The full version is Solara Home Energy, our own library case. Candidates report; not on the firm's pages
1Step 1: Read the case
Solara Home Energy installs rooftop solar and has about 180,000 customers across the US South. Texas demand for home batteries is growing with grid stress, and so is competition. The CEO asks whether Solara should enter, on one condition: at least 2 million dollars of EBITDA in year one, plus a position that lasts.
2Step 2: Ask clarifying questions
Open a question to hear the interviewer's answer.
Would we build or buy our way in?
Interviewer: Build: Solara would use its own installers and sell to its existing customers first.
Are all 180,000 customers in Texas?
Interviewer: No. They are spread across the South, and we don't yet know how many are in Texas or could add a battery.
Where would we price?
Interviewer: Near the market median, not premium.
What does launch cost?
Interviewer: About 3.5 million dollars of fixed launch overhead in year one.
Can we add installation crews in year one?
Interviewer: A little. Real scaling takes hiring and training lead time.
What do buyers care about most?
Interviewer: Reliability and a clear payback.
3Step 3: Structure your answer
Take two minutes. Lay out how you would decide whether Solara should enter Texas, then say where you would start and why.
2:00
Show what a strong structure covers
Plays back both tests: clear 2 million dollars of year-one EBITDA, and build a position that lasts.
Market: Texas battery demand and its growth by segment (retrofits, new homes, solar upgrades), and how much of it Solara can reach.
Competition: where rivals price and what lets Solara win at median prices (reliability, install speed, its solar customers).
Unit economics: contribution per install after hardware, labor, selling and warranty costs.
Capacity: installs the crews can deliver in year one, since contribution times installs minus launch cost is the EBITDA test.
Risks and rollout: permits that vary by city, a phased launch, and what would make the answer no.
Proposes to start with the unit economics, because the EBITDA hurdle is pass or fail.
4Step 4: The interviewer's next question
The interviewer gives you the numbers: capacity of 4,000 installs in year one, run at 80%, a contribution of 1,800 dollars per install and 3.5 million dollars of launch cost. Does Solara clear the hurdle?
Show what a strong answer does
3,200 installs at 1,800 each is 5.76 million of contribution; minus 3.5 million leaves about 2.26 million, just over the 2 million hurdle. A strong answer says how thin that is (the hurdle needs about 3,056 installs, under 150 of slack) and asks how firm demand and utilization are before saying yes.
Flour costs rose 18% on a $4M flour bill, and prices went up 3% on $20M of sales. How much margin did Harbor lose?
Your answer
Flour went up by about $720K and the price rise brings in $600K, so the net hit is roughly $100K.
What worked
Split the change into a cost side and a price side before adding them up.
Could improve
$720K minus $600K is $120K, not $100K: state the exact net before rounding.
Model answer
Flour: 18% of $4M is $720K more cost. Price: 3% of $20M is $600K more revenue. Net margin loss: $120K.
Next time, say this
Cost is up $720K and price brings back $600K, so Harbor loses $120K of margin.

Bain's published practice cases, item by item: level, area and what each one is, linked to Bain's page
Help a friend decide whether to open a coffee shop in Cambridge, England: structure, pick a sizing method, size the market, find the break-even volume, recommend.
A women's fashion company's revenue has fallen five years running: structure, market and consumer trends, revenue ideas, two sales options compared, then a recommendation with risks. Worked below.
The interview types by role: behavioral, a chat about Bain's operating principles, portfolio, case or coding, a take-home assignment and online tests.
Worked: FashionCo., in The five stages of Bain's FashionCo. page
A long-established women's fashion company has seen revenue fall every year for five years, and its CEO wants to know why and how to grow again before a management meeting at the end of the week. Bain's page then gives two options the CFO and CMO shortlisted: a rewards program with a sign-up fee, or discount sales three months a year. Read the official case (opens in a new tab)(read )
How you might work it is ours, not Bain's answer key.
1
Set up the case and propose a start
Play the question back and ask what success means (growth again, by when, and whether profit matters too). Lay out the drivers: the market, customers and what they buy on, competitors, and FashionCo.'s own offer and channels. Then pick a starting point and say why: a five-year slide suggests something changed outside the company, so look at the market first.
2
Test market and customer trends
Ask whether women's fashion as a whole shrank or FashionCo. lost share, who entered the market, and how shoppers now buy (online or in store, how they pay, how easy returns are). If the market grew while FashionCo. fell, the problem is its offer, not demand.
3
Brainstorm revenue ideas, then judge them
Group ideas by what they move: more customers (a stronger online channel, new styles, partners), more frequent visits (loyalty, an app) and more spend per visit (bundles, in-store technology). For each, say the upside, the risk and whether it can work within a year.
4
Compare the two options
Option A: a quarter of 10 million customers join, 2.5 million, each paying a 50-dollar fee and spending 80 instead of 100 after the 20% discount, so 325 million, plus 750 million from the 7.5 million who don't join: about 1.075 billion. Option B: three months are a quarter of 1 billion of yearly spend, 250 million, doubled to 500 million and cut 20% to 400 million, plus 750 million from the other nine months: about 1.15 billion. Check your numbers against Bain's revealed calculation.
5
Recommend, with risks and next steps
On this year's revenue, Option B wins by about 75 million. Then say what could flip it: regular sales can teach shoppers to wait for discounts, B gives up margin on doubled volume, and a rewards program may pay back over several years. Next step: pilot the program in one region and compare repeat purchases and margin, not only revenue.

The Bain interview process, and what trains each step
1
Application and digital assessment
Consulting candidates may be asked to take a digital assessment of about 30 to 40 minutes; the email after you apply says whether it is SOVA or TestGorilla. SOVA can be split across sittings, TestGorilla is one sitting, AI tools are banned, and the calculator you may use in the test is not allowed in later interviews.
For consulting roles, one or more case interviews: a structured conversation about a real business problem, where Bain says it is not looking for a single right answer but for how you think and structure. Bain's tips: clarify the objective, walk the interviewer through your framework, think aloud through the math, and listen and adapt.
Some roles include a behavioral interview, and other interviews can add questions about your past experiences. Bain asks you to come ready to discuss its operating principles and to explain why you want to join Bain specifically.
Bain publishes no round count. Candidates report a first round of two interviews and a final round with partners, whose cases are often built on their own client work and less scripted. Bain's interviewing page also lists a take-home written assignment for some roles, so ask your recruiter whether yours has one.
Missing from Bain's pages: how many rounds there are, how long a case interview runs, whether cases are candidate-led or interviewer-led, which roles get the take-home assignment, and what the objective scoring system weighs.
12 Bain-style interview questions
In our words, not Bain's, grouped by the stages Bain's own practice cases walk through, with what a strong answer does.
Structure the problem
Bain's cases open by asking you to take a minute or two to plan your approach.
1A regional gym chain wants to open in a new city. Lay out how you would decide whether it should.
What a strong answer does: Splits the decision into market size, competition, the gym's own economics and the cost to open, and says which piece decides it first.
2A grocery delivery app's revenue has fallen for three years. Where would you start, and why?
What a strong answer does: Proposes one starting point with a reason (fewer customers or smaller orders), the way FashionCo. asks, instead of reading out every branch.
3A notebook maker's profit fell by a third in two years while its market shrinks. What do you clarify before you structure?
What a strong answer does: Asks for the goal and time frame, whether the fall is revenue or cost, and what options the CEO already has in mind, then stops asking.
5Would you size the Texas home battery market top-down or bottom-up?
What a strong answer does: Says what each gives (households and adoption, or installer capacity), picks one for the question asked and uses the other as a check.
Bain allows a calculator in the digital assessment only, not in the interviews.
6A food truck sells meals at 9 and spends 4 on each; running it costs 60,000 a year. How many meals a year does it need to break even?
What a strong answer does: Takes the margin per meal (5), divides the fixed cost by it (12,000 meals), turns that into about 40 a day over 300 working days, and says whether that is plausible.
7A retailer weighs a loyalty program with a sign-up fee against seasonal discounts. How do you compare their revenue this year?
What a strong answer does: Writes revenue for each as customers times spend after discount, adds the fees, keeps units straight, and names what the comparison leaves out: margin and next year.
8An exhibit shows a market growing 40% a year while your client's share falls. What do you say first?
What a strong answer does: Reads the units and years, says what it means for the client's sales in one sentence, and asks whether the share loss is to new entrants or to old rivals.
Bain's stronger sample answers add risks, a longer view and next steps to the recommendation.
9The CEO walks in: in one sentence, should Solara enter Texas?
What a strong answer does: Answer first (yes, if demand holds at 80% utilization), two reasons with numbers, the main risk and the next step that would remove it.
Bain asks you to explain why Bain specifically and to know its operating principles.
11Why Bain, and not another consulting firm?
What a strong answer does: Names something specific you checked yourself (an office, a practice, a person you spoke to), links it to your own story and stays under a minute.
12Tell me about a time you got a team to a result it did not think it could reach.
What a strong answer does: Keeps the setup short, spends most of the time on what you did and why, and ends with a result in numbers and what you learned.

A Bain prep plan, day by day
The order follows Bain's own pages; the timing is our suggestion.
Days 1 and 2
Read Bain's pages and your email
Read the case interview page and its tips, and check the email after you apply: it names SOVA or TestGorilla.
How should I prepare for the Bain case interview, and which free resources should I use?
Train the three things Bain's careers pages name for consulting roles: the digital assessment (SOVA or TestGorilla, named in your email), the case interviews and behavioral questions. Start with Bain's case interview page and its two written cases, Coffee Shop Co. and FashionCo. On Road to Offer the SOVA-style diagnostic and the TestGorilla-style starter both start with no account, a free account includes 1 full Bain-style case with AI feedback and 1 fit session, and the worked Bain-style cases with model answers need no account. Drill case math without a calculator: Bain allows one in the test, not in later interviews.
Where can I practice Bain-style case interviews for free?
Road to Offer has 21 Bain-style cases you run out loud with an AI interviewer or step by step; your first full case is free with a free account. Larchfield Pet Cover (market entry) and Tidewell Family Dental (growth strategy) are free to read with a model answer for every question, no account. Bain's own Coffee Shop Co. and FashionCo. cases are on its careers site, and MBA club casebooks add volume. Firm-style cases are practice cases written for Road to Offer or adapted from university consulting club casebooks, not the firm's own cases.
What case interview examples does Bain publish, and how should I practice with them?
Bain publishes two of its own: Coffee Shop Co., where you help a friend decide whether to open a coffee shop in Cambridge, England (structure, a sizing method, market size, break-even, a recommendation), and FashionCo., where a women's fashion company's revenue has fallen five years running (structure, trends, revenue ideas, two sales options compared, a recommendation). Both are free written pages with answers you reveal step by step and no sign-up, on Bain's case interview prep page, which also links three RocketBlocks mock cases. Work each out loud on paper with no calculator and say your answer before you reveal Bain's. Then run a Bain-style case where you lead, with an AI interviewer: your first full case is free with a free account.
Does Bain use SOVA or TestGorilla, and how can I practice for it?
Bain uses both: its digital assessment page says the email after you apply names one, each about 30 to 40 minutes. SOVA can be split across sittings; TestGorilla must be finished in one. Bain says TestGorilla needs no preparation and points SOVA candidates to SOVA's sample questions, so a practice run mostly shows you the format and pace. Road to Offer's SOVA-style diagnostic (7 original questions) and TestGorilla-style starter each finish free with a free account; paid, the SOVA-style pack is $29, the TestGorilla-style lane $29, or both Bain lanes $49, one-time.
Is the Bain case interview candidate-led or interviewer-led?
Bain's pages don't label it. Its FashionCo. practice case asks you to propose where to start and walk the interviewer through your structure, and candidates report that Bain cases are candidate-led, so practice choosing the next step yourself. McKinsey's Beautify sample case, by contrast, poses numbered questions in a set order.
Can I use a calculator in the Bain interview?
Only in the digital assessment. Bain says a calculator is allowed for SOVA or TestGorilla but not in later interviews, and SOVA also allows pen and paper. Practice break-even, percentages and revenue math by hand, as Coffee Shop Co. and FashionCo. ask you to.
Does Bain have a written case or take-home assignment?
For some roles. Bain's interviewing page lists a take-home challenge related to your role, with likely three days to finish it and sometimes a presentation of the result, but it does not say which roles get one. Its pages for consulting describe a digital assessment, then case interviews, so ask your recruiter whether your process includes a written part.
How many interview rounds does Bain have?
Bain's hiring page says you'll have several rounds of interviews but gives no count. Candidates report a first round of two interviews and a final round with partners, whose cases are often built on their own client work.
How are Bain interviews scored?
Bain says feedback is based on an objective scoring system and that every candidate for a role gets the same questions, to reduce bias. It does not publish the criteria. Its case interview page says interviewers look at how you think, structure problems and build on ideas, not for a single right answer.
How long after the Bain digital assessment will I hear back?
Bain says timelines vary by role and office, but you can expect to hear back within 60 days. In some markets the assessment link arrives within a week of applying; if it doesn't, check spam, then reply to your Bain email.
What questions are asked in the Bain fit interview?
Bain does not publish a question list. Its interviewing page says some roles have a behavioral interview, other interviews can add questions about your past experiences, and you should be ready to discuss Bain's operating principles and why you want to join Bain specifically. Candidates report why Bain and stories about leading a team through a difficult situation, a conflict with a teammate and your biggest failure; the Bain fit interview guide has model answers for each.
Where can I practice Bain fit interview questions with feedback?
Road to Offer's fit practice: choose Bain, answer out loud, and the AI interviewer asks follow-up probes and gives structured feedback. 1 session is free with a free account; Behavioral Unlimited is $39/month for behavioral and PEI practice only.
