Flowbox Account Executive interview questions

It was a really really bad hiring process from my side. I followed up my application for 4 weeks and they replied to me after 4 follow up emails. We arranged an initial call and I was waiting for the interviewer but the interviewer showed up only for 5 seconds after 1-15 mins of wainting and then disappeared and told me I was not is the call. I think it is very unprofessional and rude and they should not behave like this with potential employee. Absolutely not recommend to apply to this company.
