Denzel interview questions

I was told the hiring process will be in 3 parts only, after I’ve completed all of those in 2 long months I was asked to do a trial day in the field. After again a long waiting time, I was told I’m hired for this position but never heard back for contract signing. This company is just starting their journey on US market I totally understand that but tell the truth to yohr potential employees that you are not interested in hiring them.
