I worked as a retail sales manager for a while before quitting my job to go back to college. I got a parttime job working for the university's IT help desk. We take walk-ins (pre-Corona) and calls all the time. Like most, my university has shifted to working and teaching entirely remotely. Before, I would have to talk to the customer on the phone while being surrounded by my coworkers and managers. Maybe this added social pressure was a good thing. I was usually able to speak fairly fluently on most days. With the shift to working remotely, I've been struggling more, maybe because it is just me and the customer on the phone. It's been getting better lately as I've become more aware of the change in my speech. It also helps that our call volume has dropped off lately (those first couple weeks were brutal with all the faculty freaking out, particularly instructors who still haven't used technology in the classroom). In both jobs, I intentionally put myself in situations where I'd have to communicate with strangers. It is definitely out of my comfort zone. I'm very aware of the challenges that I face when applying for jobs. Having a work history that requires communication is a great thing to put in a resume to show future employers that, despite the challenge we face, we're not afraid. It's good to have in your back pocket, both face to face and over the phone. As with anything, the more comfortable you are the better you'll perform. It will be scary at first, but you'll get more and more comfortable and confident. Kudos and congrats on the interview! Good luck going forward!
