Revolut Senior IOS Software Engineer interview questions

Extremely Careless - The recruiter emailed - with high words of praise expressing their desire to recruit "senior" iOS developers stating they were keen on speaking to me - following this I emailed with availability - and then in fact had to chase them post the sugary email asking me to give date/time, for the actual interview --- This should have been my 1st Red Flag. Even then, we somehow managed to schedule the actual round, which went "extremely well" in the recruiter's language, and she ended the call stating in 2 days time I will get a home test - a coding assignment for me to work on and submit. Now comes 2nd Red Flag ---- 2 days turned to 5 days and so on... So I again decided to "chase" - the recruiter once again came back via email - said to me that she has sent me a test for "Android Developer"!! Lo and Behold, they do not even check the job applications and actual email trail - with a subject line "Senior iOS developer" she is sending me a Android Test! And that too with a GENERIC email template message! I should have stopped at this, but again - I wrote back to her, politely - told her to check the actual communication and interview - and check the email trail on which she had sent generic response - and asked her to send the "correct" test, that is, to send the "iOS Test' to the person she is addressing as Senior iOS developer. Final RED FLAG Blaring in my face was now - this time, she did not even respond - I got an email from again GENERIC "revolut" email alias - stating "thank you for your interest in Revolut, after reviewing your profile, we have decided not to move ahead" - Atleast here acknowledge the interview, and then make effort to write a genuine email of rejection - if the candidate is actually rejected post interview, before sending a pretend message which is sent on resume submission! Heights of carelessness and manipulative responses, atleast they could have been genuine, accepted their mistakes of sending random emails and wasting people's time on interview calls, which later they pretend not have happened at all, since they send out generic random haphazard emails - with any random test and any random rejection. This unfortunately portrays a small unconcerned organizational mindset of the recruiters, who should be attentive, accepting of their mistakes and working professionally. AVOID and save your time!

The interview process consisted of 4 parts: 1. Introductory interview with HR, where I got a lot of helpful information about the whole process and the company itself. 2. Test 3. Technical interview which was great. No unnecessary or strange questions, if I didn't know the answer, interviewers described the answer, so it was a very interesting discussion. 4. Final interview
