Extremely unprofessional interview process. The interviewer isn't capable of evaluating and has very poor technical understanding. They scheduled 3 rounds back to back but took only one despite confirming that there will be 3 rounds no matter what the feedback is. Provided all optimal solutions to 3 problems asked but not sure what their judgement criteria is. Overall very poor and unprofessional interview experience.

It was worst interview experience I have ever had. Interview has 7 rounds spanning over 3 months. All rounds were in US time zone. After last round there was no communication for 3 weeks. I called for enquiry and was informed that they don't need a staff engineer now instead they need a lower rank role. Very unprofessional company. I will suggest never waste time by appearing interview for this unprofessional organisation
