Public Storage Relief Manager/Customer Service Representative interview questions

So apparently there are 4 steps to their interview process. Phone Call, Face to face, phone call, background and reference check. I applied online. The first phone call interview consist of going over your resume in depths and asking basic interview questions. The face to face interview was again going over your resume and asking the same basic interview questions again. The 2nd phone call is more of a math test, you will be asked what is the percentage of certain numbers so make sure you know percentages. And the last interview consist of them calling your current or previous managers asking them questions to see how well they speak of you. I made it to the 2nd phone call interview where the percentages shook me and I made mention I wasn't aware it was going to be a math questionnaire. They also look at your tenure with previous jobs and make mention that if you're not at a previous job for 3 years they normally throw your application out. I felt at this interview I wasn't going to make it to the fourth due to my flop on figuring out the percentages and being told to stay at my next job for 3 years no matter what even if the manager spits in my face. Overall very humiliating interview. Right after that they stopped answering my calls (ignored me) and 4 days later I got a thank you email telling me they chose a different candidate. BUT after the 2nd interview it was bestowed upon me that I was pretty much hired so word of advice; don't get your hopes up until you complete the fourth interview.
