Excel interview questions are not designed to catch candidates out or simply find out whether they “know the correct answer” to something or not. They are instead used in tandem with portfolios and past experiences to gauge a candidate’s experience with and proficiency in the software. As such, these questions are not “hard” per se, but they are often quite technical. If you are familiar with the software and take your time to prepare for your interview, you'll have a high chance of acing it! However, Excel is just one of a number of the most common data analytics tools, so it is not the only area you will be asked about. There are lots of other topics that will come up in typical data analyst interview questions, so make sure to study up on those, too.
