Inspiration

The first round of interview is mostly coding where we are provided problems on HackerRank or some other platform. Now the trick that many people use it, they ask some of their friends to do it on their behalf and move easily to the next round. The whole process of hiring is very tiring and involves many useful resources and money. So if cheat can be detected at an early stage, it will have multiple benefits. Major of these are:

Cutting down possibilities of Cheating
Only good candidates are passed through
Saves time and resources of interviewers

What it does

We are using several events to check if the candidate is doing cheating such as:

Screensharing through Chrome Desktop share, Teamviewer and Skype
If multiple people are present for the challenges
Using Print screen

How we built it

We have noticed some trend over screen sharing, such as when using Google Chrome it shows text at the top such as "Your desktop is currently shared with jayrodge15@gmail.com. Stop Button(Button)".

Challenges we ran into

Using Google Cloud Vision API, at first we thought it would be easy, but it turned out to be quite difficult because input type that it was expecting and the input type of our screenshots was different.

Accomplishments that we're proud of

We are successful in detecting whether the candidates are using screen share when the coding challenge is active and whether there are more than one people.
