First Round (1 hr)

1. Cows and Bulls game (code only computer’s part) (LC easy level question).
2. We get a stream of elements. Once we get an element, we have two options 1) Create new tower and place current element on top of it 2) place the element on top of an existing tower with a condition that tower elements should be in descending order from bottom to top. At any given time, find the minimum number of towers in which all elements can be accommodated.

Second Round(1 hr)

1. Design ATM Machine. (Low level design) -> Just entities and classes and interactions between them. I was asked to code few functions.

Third Round (30 mins)

1. Discussion on work experience and future goals and work at Zeta.
