Addictive game for passing tech interviews

  1. 1CA

    I've long had a dislike for leetcode interviews on both sides of the coin. Project-based interviews can also be challenging because it can end up filtering out folks who don't want to spend several hours building something in their free time. I met up with a friend last year -- a very senior dev -- who had taken some time off to study leetcode exercises while preparing for FAANG interviews. It struck me that one of the key measures of whether a candidate is a fit for a team is rather synthetic. CodeRev.app is a simple, lightweight tool that helps teams evaluate candidates using code reviews.…

    As you solve LeetCode questions, you can mark them as hard, medium, or easy. The tool will then recommend questions you should review based on (1) how hard the question was for you and (2) how much time has passed since you last reviewed it. I'd recommend normally attempting LeetCode problems and just marking them as hard, medium, or easy for you at first so the tool knows which problems to recommend you review! Here's the theory behind spaced repetition and learning if interested: https://www.codecademy.com/article/spaced-repetition

    Hey HN — we’re University of Waterloo grads, and we’re building LeetPro (https://tryleetpro.com). LeetPro is Leetcode but for soft skill-based questions and cases. In other words a platform designed to help you nail behavioral, product, and case-based interviews just like Leetcode does for technical interviews. We’re combining AI-driven mock interviews with community-driven content to create a comprehensive preparation tool for systems design, product, and business interviews. We came up with this idea just last week, and we've already launched an MVP that’s worth checking out if…

    Hey HN, Check out our technical paper here: https://arxiv.org/abs/2501.15627 and the video demo: https://www.youtube.com/watch?v=Op8hyLW7Z84 I’ve been obsessed with the art of the interview since I was in college. In my career I interviewed over 100 people and was interviewed from tech companies from startups to big tech and hedge funds. I built Neuraprep because I noticed something missing — while software engineers have leetcode.com and finance folks have quantquestions.com, other engineering domains (like ML, data science, MLOps) don’t have a go-to…

    Hi HN! ChatGPT API was just released and I'm eager to hack something with it. So I created PracticeInterview.co to help people practice for their next job interview. ChatGPT acts as the interviewer and you can choose to interview for various roles such as Finance Manager, Social Media Manager, and Software Engineer. I think this is a cool implementation of ChatGPT and the interview sessions so far has been pretty coherent. Please give it a try! It's free, no logins required, and your interview session is saved so you can comeback to it later. Since it's an MVP, I would welcome all feedback.…

    Hello HN, last week, I stumbled over an old project of mine called Click The Number. I built it about six years ago to compare my clicking and reaction speed with that of my friends. The idea is simple – just click on the numbers in orders as fast as possible. I couldn't resist and rebuilt a lot of parts again, making them a bit nicer. I updated the design and added some features like a personal high score. It lets you keep track of your own best time (which makes it ever so _slightly_ more addictive). I'm curious what you think about it, and if you have any ideas where I could take it. Have…

    A few friends and I just launched a web app to help people prepare for technical SWE/SDE internship interviews! We want to make it easier for people to prepare for interviews, especially for some of the largest tech companies. Core features include easy progress tracking, one-click link sharing, company-specific lists, and topic & difficulty-wise problem filtering. The problem list isn’t exhaustive and we are still looking for more open-source data to make our list more extensive. We want to hear about the bugs you find as this is the beta version. If you have any improvements to…
