got contacted by the nicest HR I ever met, then a series of Interviews, that started to show that they still new to this, one of this interviews was suppose to take 2 hours, but ended up in 4 hours, had technical interviews with two nice unprepared guys. then they got shocked that i have no more energy to continue a code interview. most of the interview was questions about problems they already have and need me to find them a solution to it. I thought I should send them a receipt for my time invested in their problems. then a radio silence no feedback
