Sterling Trading Tech interview questions

Received a phone call to schedule an in person interview. Very basic interview. Discussed position expectations and past experiences and why I would be a fit at Sterling in a support-help desk role. Expectation for a second round interview was given to me by interviewer. Password for a demo account to the software was emailed immediately after interview. Was told the second round would be more technical involving specific software questions. Spent hours getting to know the software post interview. I sent three emails afterword. One to thank the interviewers immediately. Two more within two weeks of the interview hoping to move the process along. Heard nothing back. Overall, big waste of time. They expect candidates to study their software with a fake promise of another interview. Very unprofessional, at least get back to your candidates.
