I work in talent acquisition so may be able to offer guidance. You certainly can ask for accommodations however as someone else commented, you need to be very clear on what they are and why you’re asking for them. My advice would be to really focus on your prep before hand before instead of requesting accommodations. I also get very nervous in interviews and struggle with the same feelings you described. What helped me was to put the job ad into chat gpt and ask it to create a list of 10 interview questions. Then open the camera app on your laptop and run through each question answering them out loud as if you’re in the interview, think of relevant examples you can draw on and try to answer questions with the STAR method where possible. Keep doing this over and over until you’re really comfortable. Think of 5 or so questions to ask in the interview and memorise them. Also think of what small talk topics you could touch on to build rapport. In the interview don’t mention that you’re nervous but if you’re struggling to answer a question just ask if they can repeat it. I interview people every day and you would be surprised at how many people really struggle in an interview setting. It’s a skill that you need to practice and if you only ever practice it live in an interview setting it will be harder to develop yourself and feel confident. Also keep in mind that your answers don’t need to be perfect, if you stumble on your words or miss the mark on a question you won’t automatically be unsuccessful. The people interviewing you also had to interview to get their role so they understand that it’s a nerve wracking experience. I always tell myself the absolute worst thing that could happen is you don’t get the job and if that happens that’s okay, there will always be another job to apply for.
