Callsign Senior Software Engineer interview questions

Initial call with recruitment. Gurjit was brilliant in explaining everything to me. Hacker rank test which was challenging however I really enjoyed. The only issue is it's a 2 hour test and I could only complete over the weekend but they were very understanding. There was a 1.5 hour technical interview which again Gurjit helped me prepare for. He provided me with excellent material which was nice to see compared to other interviews I have had.
