Interview Preparation Tips
Tip 1 : For DSA questions in interviews, start explaining from the brute force approach and then move to the optimal one. Convey your thought process to the interviewers, so that they can help you out if you get stuck. Communication skills matter a lot, and I think that is what makes the difference!
Tip 2 : Do some research about the company you are interviewing for and prepare the answers to the questions like Why should we hire you? (frame your answer in such a way that shows that your career goals align with the goals of the company), Why XYZ company?, Competitors of XYZ, etc. beforehand. Read about some latest news related to the company so that you can ask questions based upon that when the interviewer allows you to ask any question. This shows that you are genuinely interested to work for the company.
Tip 3 : Spend proper time making your resume and get it reviewed by seniors. Do not write anything that you are not confident of. Even if you write something that you don’t know, just be prepared that how you will defend it. The interviewers are much much experienced than you and they’ll catch you easily if you lie. So don’t take risks here.
Tip 1 : Try to include at least 1 development project in your resume.
Tip 2 : Do not write anything that you are not confident of. Even if you write something that you don’t know, just be prepared that how you will defend it.
