Did an OA followed by final round It was 3 hours each and were coding rounds, followed by a QnA session. Questions were based on Binary Search, Graphs and arrays. Didn't go to the Behavioural round, but the interviewers were friendly and willing to help
I applied online. I interviewed at Two Sigma (New York, NY) in Feb 2022
Interview
1st Interview - Technical phone screen (Medium leetcode question, passed)
2nd Interview - 4 round Technical interviews,
- All were around leetcode medium/hard and did well on all 3 interviews but one of the interviews was the worst interview experience of my entire life. It was an extreamly racist man that wasted 30min of my time grilling me on behavioral questions (when this was strictly a technical interview and had a 3hr behavioral scheduled the next day) and giving back unnecessary, degradding and RUDE responses to my ans such as " I don't care about that". He left me with only 15min to solve a hard leetcode question and made it impossible for me to pass the interview.
Reported this to the head of HR as it's not fair for my hard work to be thrown out the window simply because of ONE RACIST engineer.
Hackerrank challenge followed by phone screen. Answered each and every questions which the interviewer asked. Asked to find median of a data stream. Difference between process and threads,
Internal implementation of hashtable. Singleton and factory pattern. Asked about previous internships. Answered everything perfectly, got a reject mail on the next day.
Had high hopes from this interview.
