Level: Mid-Level
Round: Onsite · Type: Coding · Difficulty: 6/10 · Duration: 180 min · Interviewer: Unfriendly
Topics: Arrays, Strings, Bit Manipulation, Problem Solving
Location: Los Angeles, CA, US
Interview date: 2026-02-15
I had an onsite interview which was essentially an open-book exam. The coding questions were variations of common interview questions.
My onsite interview consisted of coding and problem-solving. The coding questions I encountered were very similar to frequently asked interview questions.
One question involved variations of string manipulation. Another question involved finding the longest subarray with unique names. I solved it using a bit mask approach. The interviewer, who had a background in testing, was unfamiliar with bit masks and asked me to explain it in detail. I implemented the bit mask solution and wrote test cases, which all passed.
The problem-solving round included many follow-up questions. I was asked how to insert a row in the middle and was required to write test cases to verify the solution. I completed everything with 10 minutes to spare.
