Had an initial call with Noom's in house recruiter which was fine and went well. 2nd round was a live coding challenge which the interviewer arrived 5mins late for then asked me a bit about myself and I spoke for maybe 2-3mins before he cut me off and said we need to start the coding challenge. He tried to explain the problem and what was required, I found it not well explained and it made the challenge way harder than it needed to be, I didn't finish in time because it took too long trying to understand the actual problem which is frustrating because the whole purpose of a coding challenge is to test your coding ability but this was more testing your ability to grasp some domain models and output basic data aggregation in a short amount of time. After my interview I never got any feedback or heard from Noom again which is a bit disappointing. Overall I wasn't impressed with the process or the company, I feel this coding interview is not long enough and the challenge could be better explained if they expect you to do it in 45-50mins.
