I applied online.
The process consisted of two rounds: DS + algo and a technical discussion. The questions were okay, but the interviewers were quite poor. They were obviously not trained to take interviews. They were focused more on the answer they already knew rather than understanding how the candidate thinks. It was more of a quiz round than an interview.
After the first interview, I gave them a pass because my interviewer wasn't very experienced. But after the second interview, which was with a lead engineer, I was convinced that the company's engineering culture is mediocre and hires people who can memorise trivia. It doesn't seem like a great place to work at, even though the product is excellent.
The process included a string-related problem and trivia questions covering the CAP theorem, distributed tracing, load balancers, and a reverse proxy.
The following metrics were computed from 2 interview experiences for the Zeta Lead Engineer role.
Zeta's interview process for their Lead Engineer roles is extremely selective, failing the vast majority of engineers.
Candidates reported having very negative feelings for Zeta's Lead Engineer interview process.
