Your interviewer will ask questions regarding your experience with various software and platforms to gauge your skill level and ability to easily navigate whatever tools they use at their company. Prepare for questions like this by reviewing the job description for clues as to what tools and platforms they want their preferred candidate to know. If you have experience using these software systems, then great! If not, then speak to the systems you are more familiar with and express your eagerness to quickly learn and pick-up new things.
