For those of you who have done a lot of questions on Leetcode (and CTCI, EPI, etc) how many questions (and of which difficulty) did it take you until you were able to easily pass the majority of your Big-N-esque interviews? You don't have to get the optimal solution to every problem. Honestly, interviewing is not as hard as a lot of people make it sound. E.g. I know that there is premium which gives you company specific questions but I only plan on buying that if I end up getting an interview with any of those companies. Just in the order they were published or should I start with the easy ones and then move on to medium/hard? . Dynamic programming was a bit trickier for me, so I just did a bunch of those questions until I had caches coming out my ears (leetcode lets you filter on some types of questions). A subreddit for those with questions about working in the tech industry or in a computer-science-related job. But I have looked at leetcode and there are currently over 1000 questions. Discuss interview prep strategies and leetcode questions I'd (probably) pass internship interviews (I've solved the ones that I had years ago with G internship interviews), but no way could I pass 3-5 difficult onsite white boarding interviews of Leetcode medium-hard. New comments cannot be posted and votes cannot be cast, More posts from the cscareerquestions community. Minimum # of steps, think BFS. Leetcode isn’t the issue here. do you tell them you've seen the problems or do you pretend that you've never seen it? Could you give a yes or no answer, please? I ended up getting that exact problem as an interview question later that day. I did a mix of easy/medium/hard, after a while I started ignoring the easy ones: http://www.learn4master.com/interview-questions/leetcode/leetcode-problems-classified-by-company.

I like the layout and "progression" feel of that site more, but I'd hate to feel like I'm not doing myself any favors by using it. Mind giving us a Google interview question and what job you were going for? The strategy that I finalized for 1st Phone Interview. I had something written up but lost it. So would you say the questions were pretty similar to the google onsite questions? I liked how you broke down problems to just one line - pattern to look for, and algorithm to use. I see there are several post from you about google interview questions, how are you attending so many interviews? Most likely they'll ask you to quickly code it and then give you another question. If you have free time, I would suggest doing at least one a week if not one a day.

If you want to focus on a specific topic such as linked lists or dynamic programming, you can just do those. There are all kinds of extremes to this answer, there are people who have solved more than 500 questions and weren’t lucky to clear the interview. I basically wrote what creatorzim said. I read the other answers, and I 100% agree with all of them. Hi r/leetcode.
