Gusto Customer Support interview questions

The interview on the phone was with Travis. He was polite, amiable and prepared with thought-provoking questions. The Take Home Test reminds me of my Take Home Finals in college, except that I had been deliberately set up for failure. It took me over 6 hours, and was clearly designed for an experienced tax professional, which I am not, nor did their job description even recommend I be. This test comes after the phone interview, but before the 1 or 2 in-person interviews (and then job offer). I think this is a sign of two things: 1) ZenPayroll thinks they are Google, and is incredibly disrespectful of your time or 2) I am completely under qualified for this job, which they should have realized through my cover letter and/or first round interview. In the middle of the test I became so bemused by how specific and nuanced my knowledge of tax law had to be to complete this thing, I almost called them and said "I'm no longer applying for a Customer Service position, but I would like to check out HR, because something is amiss here." Based on this test, IMHO, they should be hiring cheerful accountants, not people like me (who aren't accountants.)
