Interviewing.io is a platform where people can practice technical interviewing anonymously, and if things go well, get jobs at top companies in the process.

At the end of 2015, we published a post about how people are terrible at gauging their own interview performance.

After drawing on roughly one thousand interviews, we were surprised to find that the numbers have really held up, and that people continue to be terrible at gauging their own interview performance.

If you’re curious, you can see what the feedback forms look like below in addition to one direct yes/no question, we also ask about a few different aspects of interview performance using a 1-4 scale.

Below are two heatmaps of perceived vs. actual performance per interview.

Interestingly enough, how far off people were in gauging their own performance was independent of how highly rated their interviewer was or how strict their interviewer was.

As you recall, during the feedback step that happens after each interview, we ask interviewees if they’d want to work with their interviewer.
