I found the job listing in wellfound. As specified in the jd I picked a problem amd resolved it with efficiency. First I completed the problem using online compiler so I had to keep one file. I emailed the CEO and Cc: CTO as specified in the mail. Then I got the reply stating that keeping in one file is very bad and try refactoring it with some changes. I had to setup the dotnet console app and sent the refactored code. Again they said its not following design patterns properly with vague reasons. I refactored it and sent it. Again they reviewed and said some other requirements. These requirements kept changing from feedback to feedback. On 4 th change they said we wont be hiring you. Whatever the oop design principle I followed they had issues. Wasting my time completely. I trusted Gd about this as God gave me signs that the company might be toxic in terms of micro managing, reviewing each line of code written by me and judging me and I am not culturally fit for that company. I read their principles pushed to github repo, taught a good choice but it was pushed apprx 5 years ago. I figured out they don't value your time. They might be good fit for someone but not for me.
