I sent in an online application, which required a cover letter, English grammar, and reading tests. I received an Excel and presentation test in less than a week. The excel questions were interesting and fair, but they were vaguely stated with confusing wording. Don't try to ask for clarification, because they refuse to communicate with candidates. I've done several case interviews with other companies before, and most companies were willing to make sure candidates truly understand the problem they were asked to solve. But this company gives candidates an unfair test that you have to guess the real intention behind this. If you know excel skills well, the technical part is a piece of a cake. As for the powerpoint test, it is meaningless as other interview reviews said. You don't want to waste your time on this outdated formatting practice. Overall speaking, I personally think this interview was disrespectful to the candidate and how they treated candidates were not what those good reviews said about this company.
