Completed full round of interviews, 4 total. Half were absolutely horrible where the employees were obnoxious, rude and full of themselves where they would poorly and incorrectly explain what the optimal solution looked like to programming problems and would interrupt me when I was talking thru my solution. I was turned down for the role as I assume they gave me a poor review because I tried to explain things to them that they themselves were not wrapping their head around. The program they use for the system design interview is also a joke. For a tech company, they should have better software available so you can create a clear picture for the interviewer and adjust things like a professional instead of having to scribble like a 5 year old with your mouse. They also have every interviewer ask behavioral questions which only gives you half the time for the technical assessment in each interview which is horrible considering the pressure you are already under to produce a near-perfect working solution with no resources.
