Their hiring process is a total mess. Be prepared for it.

Do some mindfulness exercises, long walks, yoga – whatever helps.

Even if you get an offer in the end, like I did, the process will be taxing to say the least.

Technical interviews are, it seems, totally up to the interviewer. For example, you get some description in advance to prep for the System Design interview, but it turns out to be hands-on coding.

The recruiters are harder to reach than most celebrities.

My recruiter was de facto not replying to any of my emails. They would contact me to schedule next steps but ignore all my questions. This was even when I got offers from elsewhere and sent multiple emails to ask them to speed things up. No reply. Nada.

Ten days later: "Congratulations, you passed to the next stage, wohoo!"

Some hands-on coding, E2E system design, "Tell me about a time when you executed Klarna's amazing leadership principles as a boss."
