New: Company-Wise Interview Question Sheets for JP Morgan, Goldman Sachs, Walmart, IBM, HCLTech and Capgemini
By Preeti Verma
Knowing what a company tends to ask is one of the biggest advantages you can give yourself. The trouble is that this information is scattered across forum posts and personal blogs, and most of it is phrased as bare questions. We collected it, cleaned it up and turned it into study material.
What is new
We added a Company-wise Interview Questions section to Resources with six sheets:
- JP Morgan Chase
- Goldman Sachs
- Walmart Global Tech
- IBM
- HCLTech
- Capgemini
Each sheet has 35 questions for Java backend roles at roughly two to five years of experience, drawn from interview experiences that candidates have shared publicly.
Why we rewrote the questions
Real interview questions are often reported in a single line: "How does HashMap work?" That is not how a good interviewer asks it, and it is not how you should practise it. We rewrote each question as a short scenario that carries the same topic, for example:
- "Your service shares one HashMap across request threads and you can't switch to ConcurrentHashMap. How would you make it thread-safe, and what does each option cost you?"
- "A parking lot charges differently on weekdays, weekends and business hours. Design the pricing with separate strategies so a new rule needs no changes to old code."
A scenario forces you to think about trade-offs, which is what interviewers actually look for. Where a reported question depended on code that was not included, we described the concept instead of inventing code.
Reported DSA problems
The JP Morgan, Goldman Sachs, Walmart and IBM sheets also include a group of DSA problems that candidates report, with LeetCode links and difficulty. For problems that need LeetCode Premium, we link a free explanation only when we have found a matching page.
Also in every sheet
- A short description of the interview process candidates commonly report.
- Progress tracking. Tick questions off and your progress is saved to your account.
- A PDF download of the whole sheet.
- The AI Coach on every question, to explain a topic in simple words or write a 30-second answer.
How free and paid access works
The first three questions of every sheet are free to read, and you can see the topic names of everything else. To unlock a sheet:
- Each sheet is a one-time purchase of ₹149 (listed at ₹299), with lifetime access to that sheet and its PDF.
- A bundle of all six sheets is ₹399 (listed at ₹1,194).
- Subscribers on the original unlimited Pro plan get all sheets included.
Prices may change, so check the page for the current offer.
How to use a sheet
- Read the process description so you know the shape of the rounds.
- Answer the first group of questions out loud without notes.
- Mark the ones you struggled with, and ask the AI Coach to explain them.
- Work through the DSA group as patterns, not as isolated problems.
- Finish with a mock interview that mixes topics.
Read the company guides
We also wrote detailed preparation guides for two of these companies: JP Morgan Java backend interviews and Goldman Sachs Associate interviews.
A note on sources
These questions come from candidate-reported experiences, not from the companies themselves. Interview processes vary by team and change over time, so use the sheets to prepare broadly rather than to predict a single interview. We are also not affiliated with any of these companies.
