I applied through a recruiter. The process took 2 weeks. I interviewed at Sigma Computing (New York, NY) in Jan 2023
Interview
Started with a reachout from the recruiter. Had a brief conversation for 15 minutes, and then we never talked throughout the process. Everything happened through automated emails and scheduling links. Most engineers I interviewed with were fairly junior and seemed unfriendly with the coding language of my choice (one of the most popular languages). One of the interviewers spent 10 minutes trying to understand the output from my code, because it was not "prettified" exactly how it was expected in the question - Had to output a table, and I represented it as a map and printed the map. Spending time on prettifying the output seems like an overkill when you have 45 minutes to go through a 4-part problem. One of the engineers replied to all my discussions with a single "cool". It was impossible to interpret if I'm heading in the direction that he's expecting or no. "I think I can represent this structure as a tree" - cool "I think this tree could have a reverse edge, so it's more like a graph" - cool "I could simplify this approach by using an xyz data structure" - cool I was able to solve the problem but I just wanted to be done with the interview. The conversation was one way and I had already made up my mind not to be there even if I get an offer. That's not how a collaborative discussion works. This is not a place where I would be excited to drive to every morning.
Interview questions [1]
Question 1
Not leetcody, but you could map it to a leetcode question. The coding problems are all very similar to each other, and even though there's no language restriction, there's a pretty decent language bias, based on the comfort level of the interviewers with the language of your choice.
I applied online. I interviewed at Sigma Computing
Interview
You start with an online assessment. Then if you pass, you go to an initial screening, followed by an OA code review. The final round is a technical and behavioral interview back to back.
I applied online. The process took 4 weeks. I interviewed at Sigma Computing in Sept 2025
Interview
Overall the process is good. Interviewees are patient, willing to give guidance and response. The coding problems are written in python, and not difficult. The whole process is online assessment, bq round, oa review round, and final tech round.
3 rounds. HR round, Assessment walk through with software engineer round. Live coding session with software engineer round. Overall experience good in both the rounds. No feedback at the end.
