# Research scientist Interview Questions

In a research scientist interview, you will be expected to show that you have the necessary technical knowledge and expertise pertaining to the specific position you are applying for. Some of the common topics include basic statistical methods, machine learning concepts and case study analysis. Also, the interviewer will most probably assess your communication and interpersonal skills, which are essential for effective teamwork and funding acquisition.

## Top Research Scientist Interview Questions & How to Answer

Here are three of the top research scientist interview questions and tips on how to answer them:

### Question No. 1: What is X concept? What are its assumptions and how do you apply it?

How to answer: Basically, such an interview question asks for a textbook recall of a certain machine learning concept and its conditions and applications. Avoid overcomplicating it. Just give a simple and straightforward answer that shows that you have a solid grasp of the concept.

### Question No. 2: Provide an example of a problem you faced in your previous role and how you solved it.

How to answer: The interviewer wants to evaluate your problem-solving skills. Carefully choose a challenging situation that best reflects your ability to solve problems and explain what you did to overcome it. Preferably, the problem should be one that is relevant to your desired position.

### Question No. 3: How would you obtain research funding?

How to answer: If you had successfully secured research funding in the past, you can talk about some of the methods you used. If not, highlight the abilities you possess that can help you acquire funding, such as grant writing skills and networking skills.

### What's your strengths for this position

5 Answers### Throw a fair die 100 times, what is the probability that you will get more than 75 tails?

5 Answers↳

Umm...A die has six faces, so what's "heads"?

↳

You add up the binomial distribution for k = 76 to 100, i.e. (100 k) * p ^k * (1-p) ^ 100-k for p=1/2, where (100 k) is "100 choose k", the binomial coefficient. The idea is to figure out how many paths lead to each of the 101 final outcomes of the "tree" (which is defined by the "100 choose k" coefficients") and multiply each one by it's probability. Pascal's triangle makes things easy to think about. Less

### How to build a dictionary in such a way that it'd be efficient to search for all valid words which are permutations of a given string?

4 Answers↳

For each word in a dictionary as a value, build a key which is composed of lexicographically ordered characters. For example, value = apple key = aelpp. value = ocotopus key = cooopstu Then build an index from the keys, and you'll have all of the words that can be generated from re-ordering the elements. The result is efficient at run-time because it's constant run time. The construction of the index is also efficient because it only needs to run linearly, once. Less

↳

Perhaps use a function of the sum of the string's char codes (and its length?) as a key in a first hashtable. This key should link to a second hashtable that would directly index each particular permutation of the word. Less
