Let's not stretch the problem much and make it scarier. Rather let's talk about the potential solutions to avoid such mistakes.
Furnish your resume and projects according to job requirements. This is not a secret, but we always avoid it or use the same resume for all the job applications.
Understand the profile and its roles and responsibilities. Whether it aligns with your purpose. It should allow you to learn and grow. If it is not clear ask for an exploratory call with your hiring manager to clarify these very important points.
Know the process and nitty-gritty before you get into it. Especially understand the interviewer's background. Research on LinkedIn etc. This will give you a better understanding of the person you going to face.
The above step would also give you a better understanding of your manager in your upcoming company.
Prepare for each interview round in advance. This is very tricky and crucial. It can make or break a deal. All the above steps and hard work are a waste if you are not prepared for an interview.
We think we know all the answers to questions. But have we validated it with someone. Are we understanding the question right and sticking to the point while answering. In case our resume is getting rejected multiple times then what is wrong with the resume. What projects we should talk about in an interview and how to manage that interview stress.
For instance, you are preparing for a Data Science interview for the first time. You never want to miss that opportunity to nail the interview in your dream company. How about taking help from an experienced Data Scientist to prepare for your interview, to manage your portfolio projects, and to validate your answers. He/She can simulate the environment where one tries to trap you with the tricky questions. It can be a deal-breaker. Expert data scientists have experience in taking 100 of interviews and can share hidden agendas and tips with you.
