I have a first-round interview coming up for what I consider my dream job at a company I have collaborated with frequently over the past ten years as an external partner. I know the hiring manager fairly well and we have had several friendly conversations, although my interactions have mostly been with their team members. I'm feeling a mix of excitement and concern because the situation seems so straightforward, and I worry that I might become overconfident or under-prepare for the interview. I’m looking for any guidance on how to approach this type of interview, potential pitfalls to avoid, and tips to stand out, especially since I know there are other candidates who are just as well-positioned as I am. Any advice would be greatly appreciated!
