Nexmo Test Automation Engineer interview questions

Got contacted contacted by Talent Acquisition team via LinkedIn. First had phone interview with one of the member of this team, then I was asked to do online Codility task (preferably by the end of the week - I did it next day. I had 175 minutes for this test task (there were 2 programming tasks and then set of questions). First thing these questions were highly unusual for tester role, I didn't mind the difficulty as I've studied it all at uni, but they were more around algorithms, complexity and more obscure things that I've never encountered in Testing. I did it all in about one hour so I wouldn't consider it end of the world, but if you've never studied this, I can imagine most people must be pretty lost. I've let them know after finishing this task that I've submitted my solution (mostly as confirmation, I'm pretty sure they get notification from the testing platform). And then I've waited for almost a week. After a week I asked for feedback and was asked for my availability for a call next day. As I've tried to arrange this, I've never heard from them again and got ghosted as some other candidates mentioned here. All in all don't waste your time, it's really not worth it. Your time is more precious than that. I enjoyed the online assessment as it brought back memories from uni, but could live without the rest of the experience.
