I only had one challenge in my last job and the challenge was about I set an appointment for a client and he failed to come to the exact time for the job so he came late for the appointment and the appointment was over so he told me I should, he should go to his office, to my boss' office, I told him he can't go to his office, he has to set it for another appointment. He got mad and got angry and started yelling at me. I keep my cool and I like talk to him, I should just find a way to set another thing for another appointment. I said okay no problem. I set the following day, I set an appointment for him by 9am in the morning so he came on time and did the meeting with my boss. That was the only challenge I had in my last job.
