Karat interview for 1 hr (includes coding and time complexity questions.) This interview was organized and the interviewer was polite and helpful. I got invited for the second round of interviews in Houston, TX. This round was highly disorganized and the interviewers were confused. I went for the coding challenge and the interviewer did not know how to set up the coding environment. He wasted 10 mins doing that, and then wasted another 10 mins reading the question and understanding it. I lost 20 mins of my allocated time and was not given any extra time to finish the question. They also do not send you any link to submit receipts for expenses incurred on the trip. Do not waste your time with this company!
