HR discussion on role followed by Karat screening. Karat interview can be scheduled at any time. For Senior SDET, the process was as below: 1. Initial 5 minutes on introduction and general discussion. 2. 10 minutes question on testing. 3. 45 minutes of coding. LC easy/medium. I was able to solve the easy but not the medium. Medium is was an extension of the easy question, but it was difficult to figure out the algorithm in short time. Be aware of the time. Do the first algorithm as quickly as possible (discuss the concept with the interviewer once and start coding. No need to think out loud here, successful code is what matters) because the second one will be tougher.
