Hello Everyone! I applied to Zoho off-campus drive for a software developer role. There are 5 rounds in this interview process.
Round 1: Aptitude & Technical.
- Round 1 covers quantitative aptitude 10 questions and technical questions – code is given and asks for output – 10 Questions in java.
- Round 1 is not MCQ type, they provide us with a question paper, answer sheet (20 boxes in table format) and rough sheets.
- Topics covered in question paper – Aptitude (Percentage, ratio, profit loss, speed time and distance, average, work wages, etc…) and Technical (Recursion, loops, conditions and some logic).
- Duration – 1 hour and 30 minutes.
- Mode – written (offline).
Round 2: Basic Coding.
- Round 2 covers five basic programming questions.
- Questions paper and a Laptop are given to write code.
- Questions from all difficulty levels easy, medium and hard.
- Duration – 1 hour 30 minutes.
- Mode – offline (code in laptop).
Question asked in round 2:
1. Sort an array of 0s, 1s and 2s | Dutch National Flag problem.
2. Find the Excel column name from a given column number.
3. Goal Parser Interpretation.
You own a Goal Parser that can interpret a string command. The command consists of an alphabet of “G”, “()” and/or “(al)” in some order. The Goal Parser will interpret “G” as the string “G”, “()” as the string “o”, and “(al)” as the string “al”. The interpreted strings are then concatenated in the original order.
Given the string command, return the Goal Parser’s interpretation of command.
Example 1:
Input: command = “G()(al)”
Output: “Goal”
Explanation: The Goal Parser interprets the command as follows:
G -> G
() -> o
(al) -> al
The final concatenated result is “Goal”.
Example 2:
Input: command = “G()()()()(al)”
Output: “Gooooal”
4. Longest Repeating Character Replacement.
5. Number of Good Pairs.
Given an array of integers nums, return the number of good pairs. A pair (i, j) is called good if nums[i] == nums[j] and i < j.
Example 1:
Input: nums = [1,2,3,1,1,3]
Output: 4
Explanation: There are 4 good pairs (0,3), (0,4), (3,4), (2,5) 0-indexed.
Example 2:
Input: nums = [1,1,1,1]
Output: 6
Explanation: Each pair in the array are good.
