The first contact sound promising, the position was outstanding, but... Of course it was a ghost job, I found this after they established with me the call, and then, just 10 minutes before our call, they told me they have two candidates on final phase and we need to cancel. Also, they had the audacity to ask me to wait them another 3 weeks to see if their candidates accept the job.
