Starting an interview effectively is essential for making a positive impression. Here's a general approach you can follow, along with advice on addressing gaps in knowledge:

1. Greeting and Introduction:
2. Begin with a warm greeting and introduce yourself confidently. Include your name and, if relevant, a brief background statement about your experience and education.
3. Express Enthusiasm:
4. Communicate your genuine enthusiasm for the interview and the opportunity to join the company. Express your interest in the role and the company's mission.
5. Show Appreciation:
6. Thank the interviewer for their time and express gratitude for the chance to discuss your qualifications.
7. Brief Overview of Experience:
8. Provide a concise overview of your relevant experience, focusing on achievements and skills that align with the job requirements.
9. Addressing Skill Gaps:
10. If asked about a skill you lack knowledge in, approach the question like this:

• Honesty: Be honest about your current familiarity with the skill. Acknowledge that it's not a strength for you.
• Learning Attitude: Emphasize your enthusiasm and ability to learn quickly. Mention instances where you've successfully learned new skills on the job or in past experiences.
• Related Skills: If you possess related skills, highlight them. Explain how these skills could be transferable or how they demonstrate your capacity to learn.

1. Learning Plans: Discuss any steps you would take to acquire the necessary skill quickly. Mention resources you'd use—online courses, training programs, books, mentors—to showcase your proactive approach.
2. Questions for Clarification:
3. Ask thoughtful questions about the role and the company. This shows your interest and proactive engagement.
4. Closing Remarks:
5. Conclude with a positive note, reiterating your enthusiasm for the position and your appreciation for the chance to speak with the interviewer.

Remember, honesty is vital. Employers appreciate candidates who are self-aware and willing to learn. Frame your response around your potential to grow and contribute positively to the team despite any initial skill gaps.

Hi Aman,

Starting an interview on the right note is essential to create a positive impression and set the tone for the conversation.

Some key points that you should have in mind while starting a interview are as follow:

1. Greeting - Begin with a warm greeting, introduce yourself, and thank the interviewer for the opportunity to interview. 
2. Being Confident/Excited - Express your genuine enthusiasm for the role and the company. Highlight why you are interested in the position and how you believe your skills and experience align with the company's goals.
3. Listen - Don't get over excited and start cutting the interviewer in between. Listen to him carefully, before answering or jumping onto anything.

Now, let's address how to handle a situation in which the interviewer asks about something for which you don't possess sufficient knowledge.

1. Be Honest - Rather than pretending to have expertise, just be honest and acknowledge your lack of experience with that particular skill.
2. Suggest Supplementary Skills - It can be a case that you don't know certain skill but you know its alternative so share that with the interviewer.
3. Curiosity - Be curious to learn and show that if needed you can grasp any skill quickly and get on to work straightaway.

Hopefully this answers your question. All the best for the interviews ahead.

Think of the interview as a first date. On a first date, you're not just showcasing your best self but genuinely trying to get to know the other person. Similarly, in an interview, it's not just about selling your skills, but understanding the company and role, and seeing if it's a mutual fit.

My recommendations:

1. Instead of doing a regular hi-hello, begin by sharing a recent learning or realisation about the company.
2. Ask questions about the role you are genuinely curious about. Helps to set the tone from your end and brings both parties on the same page.
3. Acknowledge the unknown. Express the eagerness to learn. Talk about your framework that’s helps you learn new things.
4. Basic but powerful - keep a list of questions or topics you want to touch upon in the discussion. Always ask the other person for 15 mins in the end for the discussion.
