Mam how to look presentable for a first meeting with the CEO?

Ans: Please ensure you are in formal attire, light shirt, darker color of trousers. A tie... nothing too loud. Body language must display confidence. Make eye contact when you talk and enter with a firm handshake. Smile and be calm.

Ans: Read up about the company, understand the role you are being interviewed for and brush up your basics

Ans: Hi, This is Nitin. But that doesn't matter!
An interview is an interaction between you the seller and the employer, the buyer. I will give you the following quick tips..
Read up on the company and job requirements.
Carry out a SWOT analysis of yourself to know your self better.
Be confident, you will face some anxiety though. When you get tense, just say relax relax relax in your mind.
Don't underlay yourself or for that matter don't be boastful.
Remember, at the end of the day, it is more for your attitude than for the degree/ qualification you hold that you will be selected!
Rest of the smaller tips are available online!
Cheers and all the best!

Ans: Dear Jatinder,
I don't see any reason to treat two gender differently.
If there's one thing that you might want to keep a check on it would any belief that you have picked up along the way or while you were being raised where women are being treated less than a man at home or where you saw a woman at home becoming submissive to an authority male figure.
This is something that might cause an unconscious bias of you not wanting to take orders from your woman boss as you feel challenged to disobey her. Also guard yourself against generalizations about women like: Women are always emotional, women can never look at things objectively etc. This will affect your judgement and you might lose out working under an accomplished person.
Keep a check on this...other than that, it goes without saying, male or female; respect for another person and their thought processes will help you grow and thrive.

Look forward to a new learning phase!

All the best!
