Gymshark Midweight iOS Developer interview questions

I applied online via their, and around 3 weeks later I was contacted by them as they wanted to progress with me so we booked our 1st interview. There were some issues on their end so I had to reschedule my 1st interview twice but we had it in the end. 2nd stage was a technical test which I can do in my own time but it's kinda expected to be done in around a week. 3rd and final was an interview in the office with the line manager and a tech lead. This was to go over my background and what I did, then we talked about the technical test and finally it was a behavioural chat. There was a gap of around 1 week between each stage which was unexpected but the they always got back to me. Lastly I got a phone call from the talent team Melissa, (at the time) who told me the good news and after that it was up to HR to finalise the offer, make the contract and send it over. This took around 2 weeks and 2 days in my case.
