I applied online and shortly received a response informing me of the process. 1) A codility test with one task. 2) A 2.5 hour interview at their office (A codility test with two tasks and then a face to face interview)

Was notified of the position from one of my professors, company seems keen to work with universities to hire graduates. I submitted my CV and cover letter and was invited to complete a online assessment using codify, unfortunately this was right in the middle of by exams but they seems willing to work with me to give a little extra breathing space to have it completed. Unfortunately didn't make it past this point. Were generally very quick to respond to emails and provided feedback on my assessment after i was declined the position.

First there was an online 30 minute codility test, which was straightforward and had one question. Then an on-site 1 hour codility test with two questions, again straightforward. If you passed this test you proceed to the next round asking you competency based questions.
