The rejection feedback was instant, the interviewer asked two questions, Leetcode 1249. and another which I couldn't find on leetcode. The time allocated was 35 minutes for 2 medium questions. I mean at least give me 40-45 minutes, with just 30-35 minutes available and dry runs etc, if you haven't solved it, then good luck. So that's what happened, I couldn't solve the first, solved the second and instantly got the rejection feedback which mentioned the coding bar was low. This was expected, but the positive was that I was able to solve one. I mean with any question under the sun being asked, walking away with one solved was also a positive for me. I'll slow down on the leetcode grind cause it doesn't add any value to me. I'm a Data Scientist by profession and grinding leetcode adds 0 value, but will still continue on it cause it kind of feels necessary to land a job in big tech.
