Yesterday I had the worst interview experience. I am a recent graduate and it was my first interview for a graduate role and I was terrible. I had done plenty of research ahead of time into the company and its values, all the elements of the role and all the technical and nitty gritty aspects of the role. My experience matched perfectly to the job specification and I know from a similar previous experience that it's a role I would do really well in.
I felt pretty calm at the start of the interview whilst introducing myself. Then as soon as the first question was asked it felt like I was having an out of body experience. I just went onto complete autopilot and rambled on and on. My answers were completely incoherent. It was a remote interview so I had a few bullet point notes in front of me for the questions being asked and I still couldn't answer coherently. The questions were easy and straightforward as well that I had practiced answering over and over again.
I don't know how to get better. I know logically all the things to do - breathe, take a moment before answering, etc. Yet in the moment it all falls by the wayside. I thought I had grown out of my social anxiety as I have been able to give presentations to large audiences and have had examiners grill me afterwards with tough questions and coped fine. Yet a simple interview completely throws me.
