Stripe — Software Engineer ❌ Failed
Level: Senior-Level
Round: Onsite · Type: Multiple Types · Difficulty: 7/10 · Duration: 300 min · Interviewer: Unfriendly
Topics: Coding, System Design, Behavioral Questions, Debugging, Exception Handling, Geospatial Indexing
Location: San Francisco, CA
Interview date: 2025-12-28
Got offer: False
Summary
Round 1: Coding
Question: Bitfront question, which I found in commonly asked interview questions. I solved all three questions.
Round 2: Integration
Question: Replay request question, also found in commonly asked interview questions. I completed two parts, and the HR representative said it should be fine.
Round 3: Debugging
Question: A new debugging question related to exception handling. Due to insufficient preparation, I only fixed one bug. I think this round was average.
Round 4: Hiring Manager (HM)
Question: Standard behavioral questions, similar to Amazon's. I think this round went well.
Round 5: System Design (SD)
Question: Design a superhero task assignment system for saving the Earth. The prompt was similar to Uber's design. However, I had only prepared standard interview questions, and I struggled even with geospatial indexing. This is where I think I failed.
