Imposter Syndrome and I haven’t even got the job yet

I’m a Comp Sci grad looking for work. I have experience at working as a part time developer for a local business. Mainly experience in JavaScript, Node.JS, SQL and MySQL management with some experience of managing and coding a FastAPI (SQL queries through Python)

The role I applied for is a dev at another local business. However, this one is a significant step up. The salary is graduate level.

I have just been invited to a second interview which I’ve been told is the step before deciding if I get it or not.

At the first interview I got asked loads of questions regarding my technical knowledge. I’m certainly coming in at Junior level and I think they recognise that as several of my university degree alumni work there. I tried to make it clear that I had some decent knowledge in the things I had experience in and although I do have experience of other languages through my degree, it is not to the same proficiency.

One of the questions I got asked was about OOP and how comfortable I was. I have experience through university, but again not really too much from work.

I got asked what my knowledge of APIs were and I said that I managed the one at work. I almost don’t know what my knowledge is because I’ve never managed anything else. However I didn’t say that last part.

I’m absolutely terrified, part of me feels like even if I get the job. I will get there and I won’t be good enough. They’ll realise I’m not up to scratch and sack me. My last role I was one of two developers and so if I couldn’t figure something out, he was the only person I could turn to. This person had more experience, but ultimately they were my best friend doing the same degree as me.

Is this a normal feeling? I probably won’t even get the job, but the way I’m feeling right now makes me wonder if I even want it. It’s making me feel like a total fraud even though I tried my absolute best to be totally transparent.
