So you’ve lined up that big job interview … what now? Maybe you’ll do dry runs with friends, look up examples of other interviews online, or read up on the company and the people you’ll be speaking to.

That’s all great, but you could just get a subscription to Interview School.

You know when you walk through the door for your job interview, you’re likely to face some tricky questions.

Interview School uses a proprietary, machine-learning-based platform to provide targeted example questions and helpful feedback based on your answers. This way, you can prepare to ace your interview by getting real-time practice in mock interviews.

The online mentor will look at your tone, your confidence level and the content of your answers, helping you to identify weak spots and fix them. The questions are updated based on reports from real interviews at big companies like Dropbox, Slack and SurveyMonkey. You can even create your own custom interviews with the included interview builder for more precise practice.
