This was THE most unprofessional interview experience I have ever encountered.
The interviewers did not respect my time and were very rude. I don't understand why they even bothered interviewing me when they told me I would not be fit for the job based off my experience (which was berated) but tried to offer me a "possible" part time position if I "proved" myself with unpaid work and research. Sounds like bait and switch.
Be wary when interviewing with these guys.
