They interrogate references, and unauthorized references too. They only make a salary offer after interview and reference check. They offer above market rate for ivy league fresh grads, but only half as much for top talent and industry experts. The hiring manager told me that I was the best candidate he has seen in many years, then after everything, instead of salary negotiation cycles they stop communication (when you decline the 1/2 market rate offer and ask for more). This is mainly the fault of their extremist HR department that does not value skills, talent and expertise at all, and has full power over all engineering managers. Note, I got a proper market rate offer from another company few months later, so my market rate knowledge was accurate. ~$200k total comp instead of ~100k.
