Applied online with my CV, radio silence for 4 weeks. I myself had to contact them asking what was up, and got a reply from a recruiter saying that my application was "lost" due to "website issues", and was told that it's too late to do anything as there was only one spot on the final assessment centre which was due to be held in 4 days' time. Was given the option to proceed anyways and was told that I'd be contacted if they decided to hold another assessment centre. Entire experience left a bad taste in my mouth. If you're applying, make sure you stay on top of the status of your application, because they certainly wont.

They ask you just 3 quite easy algorithmic questions, it is on hackerrank so you immediately see results, no other questions, you can choose if you prefer interview or solving tasks at home.
