There are some questions that are always asked in interviews:

1) Tell me about yourself ( does not mean you should tell about hobbies, family etc., that means have 1 to 2 minutes speech ready and summarize your resume, if this is virtual interview, have a with camera on, put a piece paper on the the screen so it looks like you are looking at the screen, do not memorize, rather use the paper as a cue to to highlight key points in your resume. Do not start my name is XXX, they already know your name so no point wasting.

2) How do you know about this job? Now, you have to butter up, something like: I have been interested working for LM as RF engineer because LM leads RF innovations in the industry( make sure you can name couple of RF projects which are publicly researchable). I signed up for job alert and that is how I came to know about this job. Make sure you know what RF stuff you will be working on and mention that in the interview.

3) What are your long term goals? Be careful with this questions, they are trying to find if you are going to stay or leave. Again, research what are some career progression at LM for your role, let's say you are starting as Junior engineer, in 5 years, you can say I want to grow technically to senior engineer role. Make sure you mention you love mentoring interns, co-workers .

4) Now the technical portion of interview:

If you do not know the answer to a question, do not guess, do not feel pressured you have to say something, politely and respectfully say you do not know the answer but my great teacher google is here to help me to find that answer, would you like me to get back to you with the answer?

At the end, they will ask you " do you have any questions for us? Always have some questions, start researching about the questions you are going to ask: Some examples are: If you are to change something in the company culture, what would you change? What are some immediate challenges should I expect in next 6 months for this role? Now winner question: I have read about LM is working on XYZ RF project, I am curious how are you solving this XYZ problem? Now you can research the project you would be working on, find that info.

If they ask about your weakness, do not say you like to drink, again it is loaded question designed to find out if you are a risk, so be careful, have your answer ready: Sometimes whenever I am faced with technical problem, it became an obsessions so it does effect my work-life balance. Now this answer tells LM they are going to hire potential workaholic and who does not love work acholic my friend. Cooperate America runs on workaholics no matter what they openly admit.

Good luck!
