Qwixpert interview questions

Aptitude test, followed by 1 hour of case interview, which included guestimate, brain teasers, questions regarding my current job based on certain situations, questions on accounting since I'm a commerce student.

First was a quant round which I had cleared. Followed by a case study round and answer to why I wanted to join the firm. I submitted and gave interview to one of the current employees who has just about 2 yrs experience total and that in the company only. The interview round consisted of few guestimates, and other basic quant questions.
