First had a screening interview with HR. It's told me that I will have a short coding exercise, however I have received an extensive assessment for infrastructure work. I was thinking I am interviewing for a generalist developer position as it wasn't explicitly told me the position is about DevOps. In the job descriptions, they should be more clear about the content. They were nice enough to invite me an interview for another position that suits me better and I have received an easy coding exercise. Unfortunately, due to a small mistake I couldn't get a very high score, and next day I have been rejected. I have asked if the score of the interview or something else affected this decision, however I haven't heard anything back as feedback..

firstly your cv are qualified, then you will get an email which ask you to finish a code test online in 7 days. In the code test you need to build three functions according to its description if you pass the test (mostly finished the first 2 function), you will go to the HR interview where they will ask you basic quesions then you will go to the technique interview where they will examine your programming skills I recommand to do the coding sample before go directly into the coding test to get familiar with the coding enviroment
