For context, interviewing.io is a platform where people can practice technical interviewing anonymously and, in the process, find jobs do well in practice, and you get guaranteed technical interviews at companies like Uber, Twitch, Lyft, and more.

Over the course of our existence, we’ve amassed performance data from thousands of real and practice interviews.

Interview questions on the platform tend to fall into the category of what you’d encounter at a phone screen for a back-end software engineering role, and interviewers typically come from a mix of large companies like Google, Facebook, and Uber, as well as engineering-focused startups like Asana, Mattermark, KeepSafe, and more.

Interviewers rate interviewees on a few different dimensions, including technical ability.

With the right preparation, the technical phone interview is manageable, and top schools often have rigorous algorithms classes and a culture of preparing for technical phone screens.

Having been a founder didn’t matter at all when it came to technical interview performance.
