You get 2 hackerrank questions, while slightly difficult they aren't too bad. I didn't complete them yet was called for the assessment centre interviews. This was two 45 minute interviews, one personal about yourself and strengths and the other is a quiz on your technical experience where you get asked about OOP and polymorphism and computer science concepts. This is where my interview went downhill. Now, I do take responsibility in that I didn't prepare for it and I unfortunately memorised these concepts 2 years ago and have not looked at them since so yes, very much my fault. However, the interviewer was difficult to understand and so I answered questions that I did know wrong because I misunderstood half of what he was saying. Which again, probably my fault but then when I realised what he wanted and I tried to correct myself, he was not interested. Which, fair enough, the interviews have limited time.
However, at one point, while trying to prove that I obviously do know git (i didn't hear him say version control initially and just waffled some answer based on what I did hear) he laughed at me and said 'Don't get upset' in a very demeaning way.
Honestly the first guy interviewing me was quite awkward but fine but the second guy...yikes. They really prove the stereotype of software engineers having no social skills. So I mean if you can deal with grown men lacking in social skills and manners you'll be fine.
