I applied online. The process took 2 weeks. I interviewed at Sigma Computing in Mar 2025
Interview
HR call was very confusing asked technical questions and was very picky. Technical phone screen was even worse with arrogant interviewer. Finished all the code earlier and got rejected within an hour. The interviewer wasn't very knowledgeable when I mentioned different options and tradeoffs.

Question 1
Implement a spreadsheet class with 3 APIs, setCell, getCell and printTopN rows. Follow up questions with where to store formulas, how to detect dependencies between different cells.
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.
