Q1 linked list using recursion.
Q2)Find if a number is divisible my 3, without using %,/ or *. You can use atoi().
Q3)2 integers A and B are given, find the no of bits that need to be flipped in A to get B. ( xor a and b and count the number of bits)
Q4)Write a Rotate function for rotating elements in an array, using a reverse function.
Q5)Given 2 sorted arrays A and B with duplicate elements, get C= A -B and does not have duplicates(use a variation of merging 2 arrays and then remove the duplicates.)

Engineering test:

Q1)Given an array with some repeating numbers. Like 12,6,5,12,6

output: 12,12,6,6,5
12 shud come before 6 since it is earlier in list. So cant use a dictionary.
Q2)Implement a dictionary manually with a lil overhead.
Q3)finding nth element from end in a list
Q4)inserting an element into a sorted linked list.
Q5)In the anal part many questions were based on the rule that square root of 25 is +5/-5. Not just 5. Similarly for 1.

Geometry the questions were a little bit tricky
