Tries to understand your capabilities through work experience rather than real life scenario questions. Does not perfectly capture a candidates capabilities. Puts great value in certifications and other similar titles.
The interview process was poorly aligned with the job description. The company is trying to copy Mckinsey model but no real success stories and clients. Purely want to get the consultants from Big4 and weak interview process, no technical questions.
Interview questions [1]
Question 1
Why are you looking for a change and past experience?
1. The interview process was poorly aligned with the job description.
2. Despite completing a full system design task (notification system) and solving a DSA problem with both optimal and brute-force solutions, I was rejected with no valid justification.
3. The company seems to expect top-tier competitive programmers (like Codeforces legends) while offering compensation and stability of a typical early-stage startup.
4. Unrealistic standards for candidates, with no consideration for actual product-building experience or practical problem-solving.
