I applied online. The process took 1+ week. I interviewed at Truecaller (Stockholm, Stockholm) in July 2018
Interview
First round: skype round with HR. I had to explain my previous work.
Second Round: coding assignment. It was modified version of knights tour problem
They replied to me that my solution is correct but it does not match truecaller standards. It is difficult to imagine standards in a DS question. I asked for some more feedback but no reply from HR. They never cared to mail back with feedback.

I applied through a recruiter. The process took 4 weeks. I interviewed at Truecaller (Stockholm, Stockholm) in Jan 2017
Interview
I applied through a recruiter. After an initial HR interview, they gave me a technical assignment. It took me more than half of the day to do it (they give you 6 hours). Unfortunately, they never managed to give me feedback, they just complained that they have not enough people atm to review it (since 1 month). So I would highly not recommend dealing with them if you value your time.
