Had a phone call with the Product Manager, which followed by a frontal interview with her and 2 more people(Team Leader and the Architect).
It was a calm and nice conversation for 30 mins.
Then I was handed an exam "just fill it, it's not a big deal".
I sat there and filled an exam like a form, felt like middle school, the questions were pretty easy, like "explain a certain AWS service", or writing basic code that "adds data to a server" or "fetches data".
It didn't feel like it's testing something, and it was depended on how much they liked me on the conversation.
Hence, after a few days I got a negative response, but I didn't get the chance to prove myself, so I didn't feel like an actual interview, too bad.
