    I have been bouncing off flashcards because making them by hand has been always a tedious task. Recall runs as an MCP server - you can connect it to Claude or Chatgpt, point your handwritten or typed notes (PDFs, docs, or even a Notion Page), and it writes Q&A cards straight into a deck. You could even ask Claude or Chatgpt to research on a topic and do the same without having the need to make notes. Then you review them with the FSRS spaced repetition algorithm. Built it solo over the last 2 weeks. Stack used: Next.js, Drizzle + Neon, ts-fsrs for scheduling It's a paid product - no card…

    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…

    Hello HN! I want to share DevScreen (https://devscreen.io/). We’ve been iterating on DevScreen for a few years now with the goal of delivering an awesome interview process for both candidates and the company. We achieve this by using realistic job-based tests and allowing the candidate to use their own editor - not a whiteboard or unfamiliar online code editor. Many of the existing products in this space just bring the same old whiteboard coding puzzles to the web, without solving the core problem: those tests are not a good indicator of performance. This is a waste of time…

    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…
