Five interviews over 2 months. After 3 interviews they seemed to forget they'd interviewed me already and started again. I was too polite to correct them. They seemed nice enough during the interviews. Expect leetcode, system design and "tell me about a time when".

The process took 1 week. I got 1 technical interview with coding exercise which I did well, I was then invited to the face-to-face interview for 3.5 hours with 1 manager, 1 team leader and 2 software engineers. The interview covered some knowledge about my previous role, 3 coding challenges. I did all the questions pretty well and was very confident that I would get an offer. However, the day after that I got an email from the engineer manager informing that they all enjoyed my interview but decided not to take my application further because they were not convinced that I had enough technical depth to thrive at the company!!! I was shocked because of this unexpected result without any further feedback on why they came up with this decision. I guessed I could be because of my limited knowledge in React which they are working with. React, Nodejs or whatever can be learned in few week time and I have still been learning new stuff and get work done that way. This is the most disappointing experience in my interviews. It has been such a waste of my time and energy.
