bugfree.ai

Say you have a system design round next week and want to practice answering out loud before it happens. bugfree.ai gives you a place to do that through AI mock interviews, alongside a bank of system design questions to work from.

It is an interview preparation platform for software engineers and data scientists, and the material goes beyond design rounds.

You also get behavioral interview questions, walkthroughs of Leetcode solutions, and resume building tools, so one site covers the coding, design and application sides of a job search.

The focus is on landing roles at top tech companies. bugfree.ai is built around technical hiring, so it makes most sense if that is the kind of job you are chasing, and less so for general career advice.
