1x tech interview where you are given the basics of the problem beforehand, then the regular 4x interviews (tech, behavioral, high-level system design, low-level design) of various quality. You are told you will get feedback at the end of the 4.

Some were good. The system design one was particularly bad with a poor communicator, which made discussing solutions a real challenge.

It took up a lot of my time, and I got zero feedback after completing all 5 interviews, so I guess I didn't get it!

Wouldn't tell me the full compensation either, so it was hard to know if it was worth the trouble.

Really insane to just ghost you after making you go through all the hoops.

Also, you are required in the office 3 days a week.

LRU cache project which you refactored.
