Infocusp Machine Learning Engineer interview questions

I gave the coding test. Did not get the results of it yet. There were two Python questions with moderate difficulty levels. 1) Generate the maximum of number by adding a new digit in the given number in the proper place. 2) N- water in well, a,b,c -bucket sizes. Water drawn using each bucket will give one coin. Find the maximum number of coins we can earn.

Interview was based on mathematical and profound understanding of ML concepts. Enjoyed being asked math of ML in interview. That is one of the reason it drew me towards accepting a career here.
