Hello Womyai,

Good day to you. Hope all is well for you.
It is normal to have anxiety, we can first acknowledge that, however, we shall not let it affect us, and focus on the things that help and support ourselves:

# Focus on the interview preparation: study about the company that invited us for the interview; study about the role that we applied for; study the relevant knowledge about the industry.
# Do things that help improve your energy level during the job hunting period: exercise; reading; meditation; etc.
# Explore new things during this phase, there is no better time to explore new things during job hunting time.

During the interview, feel free to ask those questions that really matter to you, do remember that interview is a mutual and two-way thing, whilst the hiring manager are interviewing you, you are also interviewing the hiring manager. Pay attention to those small but important things like the chemistry that you have with the hiring manager; whether you can vibe with the hiring manager (as you will be reporting to the hiring manager, this is very important); what are the values and principles of the hiring manager, etc.

Best of luck to you in your job hunting friend. My prayers for your career well-being.
