They chase you up for weeks, trying to explain how amazing their company is, and that this is the opportunity you can't miss. During the interview they seem extremely satisfied with your answers and your experience, at the end you receive an invitation to their office, to meet the team, "they only need to find the best time and let you know"..... The end, nobody calls you or emails you after this.
3 months later they contact you again, with a "fantastic opportunity" and try to invite you for an interview..... for the same role, the same everything....Looks like someone erased their memory. Of course, I had to decline :)
Conclusion: it doesn't look like this company wants to hire anyone, they just received an investment, so playing with it, pretending they have roles, they need to expand etc. Maybe just to show the investor that they are "working on it", creating fake interviews and contacting people.
Be honest and stop wasting other people's time!
