When interviewing a candidate for a business analyst role, employers are looking to assess your analytical problem-solving skills as well as your communication and collaboration skills. Be prepared to analyze a business case study and answer behavioral questions that often test your ability to handle challenging stakeholders or tight deadlines. Business analysts must also be creative thinkers, so expect to tackle a few unusual brainteasers that are designed to see how well you can think through a complex problem.
How many smaller cubes are completely invisible in a n*n*n rubic's cube?
n^3- 6n^2 The number of cubes are n^3(volume). The number of cubes exposing one or more sides( 6 *( n^2) - all cubes on the sides.) Number of invisible cubes are n^3- 6n^2 .
Isn't the answer none since the question says "completely invisible"? every unit is visible by at least one side so any sub cube (made of these units) has a portion exposed.
