TP Technical Support Agent interview questions

After you complete the online application, you receive an email to attend a web-based hiring session that tells you more about the position. Once the session is complete, you have to submit another application(even if one was already submitted) You will then complete 2 phone interviews(less than 15 minutes) and if your background check and drug test are ok, you have the job. Basic interview questions: tell me about previous work experience, about a time you provided excellent service, about a time you had an angry customer.

I applied through the their own site. They sent me a mail which include all the things. Later i have had hr interview, then one more. They asked about iOS application and my background
