The process took 3 months.

Don’t waste your time. The recruiters don’t know what they are hiring for, but the hiring managers run you through the process anyways. I did the whole process only to get two automated emails spaced 5 days apart to say I didn’t make it. First was that I passed, but they were finishing the interview process with other candidates, and the second was that they would not proceed.

Process was a call with a recruiter and then a technical call with backend and frontend engineers.
