I interviewed at Sigma Computing (San Francisco, CA) in Oct 2024
Interview
I usually never post, but based on the previous posts for Sigma Computing I have to agree with the experiences that wered shared. Recruiter was quick to schedule rounds. Had 1 telephonic round which is basically a live coding session. After that virtual onsite with 4 rounds. 2 coding, 1 behavioral, 1 system design. The questions are not focused on typical leetcode style interviews. They take interviews on more "real" worlds problems that they solve. Based on the all the coding and system design rounds, they seem to lack any creativity to design different questions and all questions follow the same "real world problem". One of the coding questions felt like a question copied from a javascript interview of FAANG. Overall, it felt the interviewers were not really enjoying taking the interviews. I was interviewing for frontend position, and the company has mostly full stack engineers. During the system design round, the interviewer asked to focus more on the backend design for a frontend system design. The interviewer seemed to lack the understanding of how to design scalable frontend. My guess is the full stack engineers don't actually want any frontend engineers to get hired. This makes me doubt the engineering culture of the company and is a huge red flag. The first telephonic round felt very mechanical, I couldn't tell if I was being interviewed by a human or robot. None of the interviewers shared the positive enthusiasm you expect from good interviewers.

Question 1
I can not disclose the question - average difficulty - tailored to the problems they are trying to solve.
I applied through a recruiter. I interviewed at Sigma Computing (New York, NY) in Sept 2025
Interview
TLDR; Horrible Talent Team with no courtesy to follow up with offer for 2 weeks even after they had no negative feedback for the interview and showed intention of hiring.
Process:
Tech Coding Screening followed with Onsite - Coding, System Design and Behavioral.
After 1 week they come back to add another round of interview for me which was Architectural Round. I assumed this to be Leveling round given their feedback so far although the recruiter said they needed more Signals.
Talent head follows up after 4 days saying all good things and that they wanna extend offer. Arranged a call with hiring manager to understand leveling and job role details.
The hiring manager had no clue on my interview feedback and only went by my resume. Tells me that compensation decides leveling and that I need to follow up with recruiter on that. But given my experience, I will be considered for very-senior position.
Talent head follows with a casual email of a follow-up call in evening 4 days after which I responds to and then goes back to being MIA.
I want to highlight the great experience this company offers to candidates who have invested so much time interviewing with them and most likely low ball the ones who will be hired too.
I applied online. The process took 2 weeks. I interviewed at Sigma Computing (New York, NY) in Jul 2025
Interview
Pretty basic. I applied online mid June 2025 and got a call with the recruiter pretty quickly.. then had 1 telephone coding interview .. got the rejection message after then within a day.

Question 1
Implement get and set methods on a spreadsheet class and retrieve first n rows.
Then improving on that add formulas and execute based on other cell values
An initial call with the recruiter and then the 60min virtual technical phone screen. After that, the full loop of 2 coding rounds, 1 systems design, a behavioural and then a debrief.

Question 1
Make a spreadsheet class, where you can write numbers into the cells, create formulae where cells depend on other cells, etc.
