Just a waste of time. These guys should be more organized with the times and schedule for the study before recruiting participants. The lady on the phone gave me the dates which did not match after I completed my screening process. Too late as I already made arrangement with my workplace for the dated she promised. I also wasted 3 hours of my Saturday morning for the screening process. Arrived at 7.30a.m in the morning to find out that I’m the first person in the parking lot. At least they could have reimbursed me for the time I spent for the screening process. What’s the point in asking for people’s available time for the study when they don’t take it in to consideration?
