Had three interviews 1. Phone call with team manager asked about past experience and also about personal projects about 30 minutes 2. A 1 hr and 30 minutes of a system design interview mainly in the AWS domain with 1 easy coding question at the end 3. A codility test with 3 questions 2 were mediocare to easy level and one was kind of hard, now I for sure passed these three questions but for some reason they told me that I didn't pass them and specifically the two easier questions rather then the hard one which is weird. overall experience was okay they replied fast after each interview But I don't know why I didn't pass the codility test for sure I did everything correctly and efficiently.
