I applied through university. I interviewed at SingleStore in Aug 2025
Interview
Asked to open an open source code base and add a functionality. Felt like the interviewer already made up their mind to reject me. Interviewer was dull and unengaging. Very boring. Answered all questions but to no use.

Question 1
How does malloc() work internally? What’s the difference between malloc, calloc, realloc, and new?
Couple of coding interviews, pretty standard. One was different from the normal and a very cool interview about an existing in memory database. The process is quite long but that's how it goes at good companies sometimes
