At the end they asked me a data structure question You are given a list of strings , find the anagrams (not sure if the guy wanted me to compare every 2 of them) , time complexity of that etc , by that time I kind of understood they have a different requirement so did not try much for this question. 7.

Some of the gists that we are fetching have anonymous owners, which in turn means we don't have the owner's image to load for the gist. Switch to use GithubApi.getGistsObservable() as your api which will return you an Observable instead of Call object. Make sure the app behaves as it is supposed to with the new method of fetching the data. Filter out the gists with no owners/images Optimize the adapter in charge of populating the list

You are given one method that does all the work to pull in "x" bytes of text at a time. This next method takes the output from that first method and you need to complete it so that it prints out each full line of data, up until the line break is reached.

I was given a problem involving an integer array, and the goal was to transform it in a way that required careful thought about time and space optimization. While discussing my solution, I suggested using a hashmap for optimization (which is wrong to begin with), which led to a follow-up question about how hashmaps work internally and I couldn't answer it.
