A lady called me and asked me about my expectiation. Then she asked me salary. After I said the number (which was an average number for engineers with experiece in cloud computing), she directly said I don't match their requirements. After saying thank you she hang up the phone. I have to say it's very RUDE!! I've been to many interviews and none of HRs was as unprofessional as this lady. The whole process only took 2 mins. I can't believe I waste two minutes on this non-sense call.

3 rounds, first phone screen, second algorithmic problem solving, would say mid level difficulty, 3rd interview about tech knowledge, some system design question and in depth questions related to the projects that the interviewer have done before.
