Facebook Hacker Cup 2013 – Balanced Smileys.
1. Arrange the text into a justifiable format with fix length. The question was easy to level but very long as you have to count the spaces in between and then create new sentences depending upon the length passed into the function. I implemented almost all the conditions and explained the implementations and conditions but still was not able to complete the output. 2. Create an LRU cache and show it in action. Implemented the whole logic and showed them a working prototype. Looked kind of impressed but the last feedback was not good.
I do not feel that I should disclose the actual questions, but they were definitely the most fair of any interview I received. I felt like it was super positive environment where they want you to succeed. Make sure you are familiar with basic data structures (stacks, queues, graphs, trees, etc) and your classical n log n sorting algorithms (merge sort is a great one to know for every interview not just Yelp). They also give you a lot of opportunities to show that you know things. Just go with. Verbalize your thoughts and tell tidbits of knowledge along the way. But get code on the board. I feel like Yelp really wanted working code on the white board, and you have a very limited amount of time. Practice on an actual whiteboard with an engineer before if you can. Whiteboarding is never the easy. Seriously check your markers between interviews or bring your own. There is nothing worse than a marker going out during thoughts. I have heard that someone asks you to make a search engine (preprocess and make files into an inverted index) for Web Dev interviews, but that was not the case for mine :)
Was a coding exercise so no real questions
