10 min call from recruiter that noticed me on Linked In.

30 min call with hiring manager to get some background information from me and describe the company / role.

30 minute call with senior engineer to do a generic technical screening problem

4 hour onsite interview with 2 people at a time, for 45 minutes per round. 2 / 3 rounds were logic puzzles, high level architecture questions, and a technical problem solving session with a problem they face internally.

The other round was more background and behavioural for culture fit.

Overall I enjoyed the communication and method for assessing my skills and fit. The only part I did not enjoy (and hence the negative review) was the way it ended. The recruiter ghosted me with no feedback which I would have liked, but at least a courtesy email would have been nice.
