The interview process has multiple steps. For me, those were:

• Online logical test
• Talk with recruiter
• Online coding challenge

After the coding challenge, they decided not to proceed.

I really enjoyed meeting and talking with the recruiter. They did a really nice job outlining the process and presenting Klarna.

The part I did not like as much is all these online tests. They take away the option for discussions and asking questions about their practices while you're implementing, which could lead to a better experience and solution.

They are designed to be done in a single go. They aren't really hard but require some focused time, so take the time needed. The evaluation criteria seemed a bit stricter than I expected. I don't mind that, however, and I appreciate that they passed the feedback about their concerns.

I also understand that this is probably due to high demand. And I guess we accept the rules of the game when we apply. :)

Overall, it's an experience, and part of the process is also to figure out if the match works for both sides. In this case, it did not.

1. Logical questions

It's a short pattern recognition test.

1. Coding challenge with 3 tasks:

1. Function gets two strings (first, second). Figure out if the second string is a rotation of the first and return the number of rotations.
2. Function input is a string of numbers, separated by spaces. Return a new string with the same numbers, ordered by weight (sum of all digits in each number).
3. Input is an array of arrays. Find a logical order for the elements based on the conditions in the task.
