conducting multiple interviews at the same location (read: faking at their place)
changing location while conducting a single interview (read: trying to fool the time stamps by responding slowly while in car; filling in the gaps at home;...)

Please not this is only a single indicator and must always be taken with grain of salt. It is possible for a single interviewer to conduct multiple interviews at the same location (e.g. at the office, at the bar,..), but they should be able to explain it.

The code

A full solution that works on all three major computer operating systems (Windows, Mac, Linux) is available in Python/ folder. To run it, you should habe Python V3 or later installed.

Using the Python version is recommended for first-time use

If you have at least basic understanding of computer scripting, you can also use individual code snippets for Win, Lin or Mac in the appropriate subfolders.

Requirements

Linux:
No special packages aside the usually installed stuff: BASH, NetworkManager, any hashing algo (example uses xxhsum)
Mac:
No additional packages
Windows: WinFii from https://github.com/changyuheng/winwifi should be installed to enable non-admin users to scan for WIFI networks.
