I attended an interview for a role with 3 years of experience.

In the first round, they asked basic HTML and CSS questions, such as attributes, the flexbox model, and responsive design. They also asked about my project experience. I tried to answer all the questions and got selected.

In the second round (HR round), the HR asked about my project. When I started explaining, she stopped me and said, “Congratulations,” mentioning that she had received positive feedback from the technical team. She told me I would get a call from HR for further details.

The next day, I got a call from HR. He asked about my education and work experience, and he said he would call me the next week.

However, I didn’t get any updates the whole week. So, I emailed them to ask about the result. They replied that my feedback was positive but, unfortunately, they couldn’t move my application forward.

I’m still wondering what went wrong.

What is the approach that you are following? Waterfall or Agile?
