Weekend Health interview questions

They kept following up with me regarding a position for weeks. When I was ready to take the interviews, they asked me to do a coding problem. I followed the instruction and wrote a code in Java. Then they came back to me and asked me to convert it to python and add a readme file that I did. I rewrote the algorithm in Python and added a detailed readme file with all different sections from Intuition to time complexity and edge cases. It took a week for them to review it and came back with a weird feedback that although it was good but "there were not enough positive aspects". Then they said my code had some mixed signals and didnt have enough comments. Looks like they don't know how to read a code or they don't know to refer to a readme. I had about 20 lines of explanations in readme file about my approach and test cases. Seems like they just want to waste candidate's time.

Interview process was easy and straightforward. The job posting listed "competitive salary" but after 3 interviews, they offered a salary about 30-40K below average range for experience and position. I did not accept.
