The Technical Interview Readiness Assessment (TIRA) is a free 45-min adaptive assessment helping SWEs understand their exact skill profile and companies they're ready to interview for — packed with actionable feedback to get technical interview ready.
I recently tried TIRA and found it to be an excellent tool for evaluating someone's skills and readiness for interviews. One suggestion I have for improving the user experience is to add a zoom out feature when tracing code snippets, especially when parts of the snippet get hidden while scrolling up and down.
