There are 5 rounds of interview. One HR screening, one HM behaviour interview, one pair programming, one system design and one culture fit round. I only progressed to the pair programming round. I completely bombed the interview as my mind went blank. The HM behaviour interview is fairly easy. The pair programming wants you to write from scratch a server with Gin framework. In hindsight, it is probably not that difficult, but writing everything from scratch caught me so off guard.

Write a server with the Gin framework.

How do you test the code?
