I first spoke to the recruiter whole depicted the company as place to be. I was then given an online task, only to be rejected for not printing a final string to the console. The whole algorithm was correct but was declined for a console print.

Terrible HR. I was contacted on my work mail for an interview at Spendesk, it's quite obvious I woudn't reply back from that but from a personal mail address. I even managed to set the calendly appointment but the HR never showed up. Not even one email back sent to me. If this is how they work within the organization, then run and don't look back.
