They contacted me out of the blue and had me go through one phone interview, their culture introduction and quiz on their website, a HR round with a recruiter, and a coding project. After I passed all these, I was put in another phone interview. (Note: I am in the West coast.)
Remember, these clowns were trying to recruit me. I was at that time working as a Research Scientist in X in one of the big firms over in the West coast.
A good part of the interview was spent by them disparaging X. Then they ended the interview with "We have all the information we need, we won't be calling you."
I felt like I had been hazed by a couple of dimwits who were not even that good at it.
This article assuages my worry that I was being unreasonable.
