The interview process was multi-faceted.
Scheduling: took too long - from discussing scheduling it to actual interview date, it took ~2 months, way above average. In comparison, both smaller companies (e.g. start-ups) and larger (like Amazon, Google, Facebook) took 1-2 weeks tops to schedule (virtual) on-sites.
Interview day: was one of the longest days I've had. 8 interviews (Google and Facebook have 5 interviews, in comparison), with non-existent breaks between the interviews (unlike average of 5-10 minutes, with Google leading with mandatory 15 minute breaks between interviews).
Coding questions, design question, behavioral, guided discussions of solving coding problems, and sample code reviewing on GitHub.
Overall, the experience was nice, and Indeed gives you plenty of feedback, which is great.
Downsides:
1. Under leveling happened (big time) despite 2 years ago being pressed on applying at higher levels
2. Interviewers seem to be looking for very specific things that they have in mind, and its unclear what that is, and are often judging you very subjectively, compared to data-driven like other employers
3. Resume "deep-dives" are very subjective - managers either like you, or don't. They ask probing questions that you cannot often answer without violating confidentiality agreements with prior employers. Too much stress on "show me what you've done", which works for some candidates but not all, as opposed to "show me your skills, thought process and potential"
I respect their process, but it's not for everyone.
Unlike other companies, I recommend candidates be upfront about salary expectations. While Indeed gives employees more time off than their competitors, benefits are otherwise average and financial compensation on the lower end.
Friends who work there say great things about the company. So would not dismiss it, but it really depends on what you want from your career.
