"The questions you are asked in an interview for a position as a scientist will depend greatly on field of science you intend to work in. Generally, interviewers will be interested in your formal education, field of study and specialization, work, internship, and research experience, scientific writing skills, and interest in the subject matter. Expect to be asked technical questions that pertain to the knowledge needed to perform the duties of the job. While there are some positions open to scientists who possess associates' or bachelors' degrees, most jobs will require you to have at least a masters' degree with the majority requiring you to have a doctorate."
Programming question: find the number of connected components from 2-dimensional grid (mark 1s as component, 0s for others).
I did the program in Python quickly using 2D array search and if-else conditioning. The interviewer agreed with my solution. However, he did mention that if I can do it in C++, it will be even better.
