On 25th Nov I received verbal offer from the HRs, which I accepted. I was told to send medical check from the previous employer and the agreement will be signed on 28th Nov, because I'm supposed to start just few days later, on 1st Dec. 28th Nov CTO calls me to lowball the offer over 20% from the settled salary. When I said that just before the weekend I already agreed to their higher offer from the HRs, CTO *STARTED TO PRETEND* that he cannot hear me over the phone and hung up! After I tried to call him back, he didn't pick up the phone. Few hours later (I made a few phone calls without reply and wrote one email) finally HRs called me back to tell me that actually somebody with higher experience agreed to work for lower salary, and they choose him instead of me. Avoid them.
