I got a offer letter from a company that claimed itself to be a game development studio. They hired me on the basis of a test project they had asked me to make, to test my skills. After completing and submitting the project I got selected.
I was never interviewed at their place and only had talked with the Co-Founder on phone. When I arrived at their 'office' at the first day, I was shocked as it was a really small and filthy cabin with only the co-founder and one more person in it, no AC or ventilation or even clean toilets/washrooms to use.
I left within 2 hours and never heard from that co-founder again. But the offer letter they game me was legit, it was well-written and really gave me the impression that I will be working with a decent company.
Can I show this offer letter in any future interviews or say that I'm currently working at this company? What will be the downsides of doing so? Thanks!
