Group 8A interview questions

I got 2 rounds, First goes well, and in Second round I've been assigned with coding test, In which they asked to demo 3rd party API call, Task 1 was to just call API, get data and categories them, in Task 2 it was just same API and get Data into pagination. So, I just made it easy and combined both into one to demonstrate code resuablity fundamentals. And for that reason they have not selected me, Seroiusly? Dont just waste candidate time if you dont have enought expeirenced interviewer.
