Show HN: I built an AI tool to practice technical interviews with

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 platform to prep for interviews. Sure, there’s Kaggle and Coursera, but nothing unified.

So I spent a summer collecting 400+ real interview questions and built detailed answers for each. I drew from academic sources, online communities, and LLMs to refine the content. Then I used this dataset to build an AI that mimics how a human interviewer evaluates responses.

Here’s how it works:

• The reasoning engine extracts core ideas from the user’s answer. • It compares them to the expected ideas from the database. • If something is missing, the conversation continues — just like a real technical interviewer would do.

With recent voice and reasoning model advancements (thanks Sesame, O3), it now runs on-demand phone interviews that feel surprisingly real.

Show HN: Squadbase – Private Streamlit/Next.js AI apps in 3 min

Hacker News - Fri, 05/02/2025 - 10:13am

Squadbase lets you push a Streamlit or Next.js repo to Git and get a private, authenticated URL—with RBAC, logs, and analytics—in about three minutes.

Hi Hacker News, I’m Naoto; my team and I built Squadbase after feeling this pain ourselves.

I once shipped every product with a matching admin console, but now teams mostly want internal AI tools—small, LLM‑powered apps that automate their own workflows. They’re quick to code, yet hard to deliver: sharing one safely means wiring up auth, RBAC, secrets, logs, and analytics—easily 10+ AWS/GCP services—so we spent more time wiring than building.

So we built Squadbase. You focus on AI logic; we handle the infrastructure:

- Git‑based CI/CD (auto‑deploy on push)

- Built‑in auth

- Per‑app RBAC

- Runtime & access logs with alerts

- Usage analytics dashboard

- In‑app feedback widget

We launched this week and would love your candid feedback. Your first deploy takes about three minutes—just connect a GitHub repo. Free for up to 5 apps and 5 team members:
