Sarvatra Technologies Senior Software Developer interview questions

Worst interview process ever. They kept me waiting for 1.5 hours saying the panel is coming for interview, it seemed like they were not aware about my interview schedule. They took my first round where the interviewer was least interested in taking the interview and was searching for questions to be asked. Second round was scheduled the next day in which the interviewer was very unprofessional and was asking abstract questions and expecting pin point answers. Worst interview experience ever. Both rounds were conducted at their office.
