Top 15 Frequently Asked Data Science Interview Questions and Answers. from datasciencefieldofstudy.blogspot.com

A question is a question which seeks a response or answer. Everyday, people are asked to being asked questions. Some questions are open ended with the need for explanation, explanation and more, while some questions are closed and only require one answer: Yes or No. In some instances others ask questions that do not necessarily require a reply but only for someone to listen to (rhetoric issues). In the case or question being asked, the answer will have to be able to explain what it is that the questioner is looking for.

Before you plunge into answering the question, make sure you are clear in your mind about what the question is about. It is not a bad idea to start by seeking clarity over what is being asked. If you are asked politely "I am sorry, I'm struggling to know what you're trying to say If you could rephrase the question, what would you suggest?" It is easier to communicate in such situations than speaking in the same voice with no awareness or wisdom. The purpose behind answering questions is to contribute positively to the person searching for an answer. Do not waste your time. Seek understanding first.

One method to increase the effectiveness of answering an inquiry in a pertinent and objective manner is when you give the person asking the question the time to finish asking. Some people may take their time to describe precisely what they want to convey. In answering a question prior to it is thoroughly asked can appear unprofessional. Don't assume that you know the direction that the inquiry is heading, so you want to help the person to clarify the issue. If you're time-bound, let the person "ramble" while you record key things. It also gives you time to formulate and come up with one of the most suitable answers to the question. Listening skills give you an impressive success rate in the answer to questions.

You have to establish if you're qualified to answer that query or if somebody else is. Can you legally speak about the subject (journalists can haunt you even if you're expected to be the company spokesperson)? How long should your answer be?

It is possible to help the person waiting for to answer you by asking "Let me think about it ..., Let me see ..". This will ensure that the person does take a break from thinking that they aren't hearing the answer, and instead you're simply ignoring etc. It also allows you to think of statements which you'll not regret regarding later. You can identify the most effective way to present your argument with wisdom without leaving scratches or fresh wounds.
