Taverna interview questions

Submitted my resume via email. Was contacted by an employee via phone who interviewed me and then asked me to wash dishes that night. I told the employee I was already committed to another employer for that night but could come wash for Taverna in two days. I texted the employee two days later to confirm that I could come in and wash and the employee never responded to my text. I also texted the employee before that to obtain more info about the job, but his response times to my texts were extremely slow so I decided to stop pursuing this employer - as they seem like more trouble than they are worth.
