I’ve just been invited for an interview as a junior developer.
But there is an algorithm section to the interview and I’ve only done the basic algorithm part of FCC.
What are the best resources to get quick practice? I’ve only got a week until interview 
Redo the Basic Algorithm section by resetting your code and also work on the Intermediate and Advanced Algorithm sections. You can only do and learn so much in a week. Give it your best shot, because that is all you can do.
schedule a mock interview
listen to their advice
and crank it up, son!
You can always try HackerRank or CodeWars if you need more challenges. But there’s probably enough to keep you busy all week on freeCodeCamp.
