Has anyone did work for this company? I am fairly new to mystery shopping, but have completed jobs for a few companies. Sentry was on of the first companies I signed up for but never saw any jobs that interest me. I received an email from then about some shops in my area and one interested me. I applied for it but received a response that I must pass the certification test. I took the test and passed, and let Sentry know this. Never received a response, but a few days later received an email that there were shops in my area and the shop I applied for was on the list. I applied for it again, but no response. Have decided to pass on this company. Cannot work for a company with communication like this.
