Moonpig Android Engineer interview questions

First round was basic android engineering discussion, Second round- Kata based pair programming, they rescheduled interview time twice but same day, easiest question, I thought I aced it, gave me 75 minutes to solve the problem,I finished and all tests ran within 50 minutes, buy I think the recruiting team is not interested in hiring for the position, as I can see the position is still open, their feedback was not very clear on the interview, besides the recruiter is not very good in responding email, since I was new to Kata based problem solving had to put some time on it, but I guess they don't re wasting someone elses time
