The main thing that jumps out to me is the memory issue they asked you to address was not addressed.  

In your readFile, you have 

with open(filename) as f:
       content = f.readlines()

Which reads the entire file into memory. They specifically did not want you to do that.  
The implication is they were looking for a solution where you read the file maybe one line (or even one word) at a time and look for anagrams in smaller groups.
