SQL Interview Questions and answers Part 2 Amazon SQL Interview from www.youtube.com

A question is one that solicits for a response or an answer. Every day, you are able to receive questions. Certain questions are open ended that require explanation, clarification and etc., while other inquiries need only the answer "Yes" or "No. In some cases, there are questions that do not necessarily need a response, but are simply an audience to listen to (rhetoric inquiries). Depending on the format or question being asked, the answer which follows must answer what the question is looking for. Many students fail their exams not because they're boring but because they fail to be aware of the information being demanded of them. The failure to convey the issue properly can result in an uninformed action or response. After an event, you will feel comfortable when people have questions. It could be a sign that the audience was engaged with what you were presenting and that your event drew interest from others. The way you handle those questions will boost your audience's opinion on you or increase their confidence in the quality of your product or services. As a professional, you'll be required to master what it takes to be able to answer pertinent questions but most importantly how to respond to questions efficiently.

Before you get started on answering a question, make sure you're clear in your mind about what the question is about. It is not a bad idea to start by trying to understand what's being asked. Request politely "I apologize, you don't seem to get what you're saying Would you mind changing the way you phrase it?" Your communication will be better with this approach than being unable to speak with awareness or wisdom. Keep in mind that the purpose of answering questions is for you to be a positive contributor to the one who is searching for an answer. Don't take time. Seek understanding first.

One way that can enhance your ability to answer the question in a meaningful and objective manner is when you allow the person asking the question enough time to finish asking. A few people take time to describe precisely what they want to know. When you respond to a question without knowing what is properly asked might seem unprofessional. Don't think you know what direction the question is going hence you wish to help the person in getting to the bottom of the matter. If you're on time allow the person to "ramble" while you make note of the key elements. It gives you the time to synthesize and think of your best solution to the question. The ability of listening gives the highest success rate with regards to your answers to questions.

It is up to you to determine if you are qualified to answer that query or if somebody else is. Is it your right to speak on this topic (journalists could be a source of trouble even though you're not suppose to be the company spokesperson)? How deep should the answer be? A few moments of silence will show that you're just making up whatever material you have in your mind, but a thought out answer is in the pipeline. You can actually prepare someone for an answer by using the phrase "Let me think ..., Let me take a look." ..". This will ensure that the person does do not just sit and think that you didn't hear but you're actually ignoring, etc. Think through your thoughts and you'll be able to come up with statements which you'll not regret for later. It is possible to identify the best method of answering with wisdom without leaving scratches or fresh wounds.
