Bad experience with Codingame Kotlin Tests

So for a few weeks I’ve been looking for a new job.. and I landed some interviews with good companies.. most of these companies have two steps in their recruitment procedure.. the first is an interview with someone from HR and the second part is technical test.

Now the technical test is almost always a Codingame test.

I’ve been a developer for almost 3 years..I’ve worked mostly with KOTLIN. However, I could never pass these tests.. like I tried hard and for some I even studied the basic stuff.. still nothing..

Anyone had such an experience? And can anyone help me with some tips on how to pass these tests?

PS: I almost always do great in multiple choice questions.. it’s the coding tests that I fail.

Thank you so much in advance
