It was pretty easy. Practice problem solving, practice what have you done in your previous company, and so on. Follow, many websites like leetcode, interviewbits and other online resources. Very important thing is to prepare on your CV properly. Double check what you put versus what you know/ practice.

The process was strait forward. Talked to a recruiter, had a take home test, turned it in and talked to a VP of engineering on zoom, then had an onsite interview.
