One of my friends has a saying that is very difficult to translate to English, but a fair translation would be "everyone has different memories of the party". The point is not to use anecdotal evidente as absolute truth.

Maybe a few rounds of interviews with each company could help to paint a better picture. Personally I could say me interviews with Amazon have been some of the most pleasant I had so far, while other companies have arrogant engineers that ask incredibly hard algorithmic problems that you would hardly ever find in real life.

Just because I had one bad interview doesn't mean I should write off the entire company.
