First is 30 minutes phone screen. After passing the screen, it's a 45 minutes coding interview with a company called Karat. Some concept questions followed by coding questions. Coding questions has different difficulty levels. If you solve the first one, you get a harder question.
Three technical interviews and one behavioural interview followed. Everyone was genuinely nice, including the recruiter. The process felt smooth and well organized overall, and I received an offer about a month after the interviews concluded.

Interview
Recruiter Call, Karat Technical Interview, I didn't get past the technical. The Karat software was pretty buggy, especially with muting your mic. Every time I tried to mute, the audio of my interviewer turned off too.
Pretty standard process. Had a call with a recruiter, then a more technical karat round, then finally the virtual onsite 3 hour interview. No curveballs. All I would say is to learn about MongoDB.
