Compiled by Padmavathy. M

The below is a compilation of the on campus placement experience of the author, a final year IT student at MIT. She was recruited by Multicoreware Inc. She shares the experience of the company Zoho here. It was an intense process spanning 3 days.

ZOHO( 3 days) : Criteria: 6.0 above. 

Round 1: Written

30 Output of C programs with no choice. 10 (2 marks). 20 (1 mark) full loop programs with pointers

The questions were challenging and covered all C concepts.

Round 2 : Coding

Around 150 students shortlisted for this round. It was a local machine coding round. A staff will be assigned to a group of 5 students. He made note of the time each student took for solving each question. There were totally 7 questions and I solved 4 questions within that time. The given compiler was turbo C. No library functions are to be used

1) Alternate sorting: Given an array of integers, rearrange the array in such a way that the first element is first maximum and second element is first minimum and so on.

Eg.) Input: {1, 2, 3, 4, 5, 6, 7}

Output: {7, 1, 6, 2, 5, 3, 4}

2) SECOND QUESTION WAS A VARIATION OF THE ABOVE ONE (EXTENSION)

3) Remove unbalanced parentheses in a given expression.

Eg.) Input: ((abc)((de)) Output: ((abc)(de)) ; Input: (((ab) Output: (ab)

4) Check whether a given mathematical expression is valid.

Eg.) Input: (a+b)(a*b) Output: Valid ; Input: (ab)(ab+) Output: Invalid ; Input: ((a+b)Output: Invalid

5) Form a number system with only 3 and 4. Find the nth number of the number system.
Eg.) The numbers are: 3, 4, 33, 34, 43, 44, 333, 334, 343, 344, 433, 434, 443, 444, 3333, 3334, 3343, 3344, 3433, 3434, 3443, 3444 ….

Round 3:

Complex coding phase 1

Matrix related question with multiplication between numbers like a bot can move 8 options up, down, left, right, cross up, down, etc questions were like with diagonal, without any diagonal

Round 4:

Complex coding phase 2
