The interview starts with CV screening,(~1h), after you are assigned to an Karat system(1h) it is interviewing the candidate with system design questions, and 30m algorithm(it was subdomain visit), and afterwards, your interview process starts with real persons. (4*1 hour) And system design was for Shazam first, afterwards It was API design for automated parking lot system, 1 hour of algorithm interview (palindrome, finding the longest palindrome in given string), and behavioral interview. Feedbacks (30m) Pros: If you want to feel the long interview processes before reaching out Amazon, Facebook and so on, It is free to test yourself. It is good for this purpose. Cons: If you really need job, please dont waste your time. It is useless, they are not really looking for good candidates, they are looking for someone automated like robot and answering the whole questions. It is 6 hours interaction with people. A lot of stress, preparation and at the end not really with proper feedback, somewords like feel free to apply again. PLEASE dont waste your time.
