Applied online, thrilled to receive call the next day to set-up interview the following week. Performed the math tests, was in the first batch of people called for 1 on 1 interview. Basic questions about background, how others would describe me, strengths/weaknesses. Then we discussed the mechanics of the position. The hours, the holidays, call center environment, growth opportunities. Then told "Next step is meeting with a manager." Left feeling confident, only to be deflated by reading glassdoor comments about the Interview continuing the same day. Received generic rejection letter with no explanation 10 days later. Did I bomb the tests, am I too old, is 15 yrs of customer service experience too much/too little? Still confused.
