Interview preparation journey

Journey

My journey started when I was in college, and I saw all my friends learning new coding languages and developing new projects. After seeing them, I also started to learn and code.

Application story

I received that opportunity from LinkedIn Jobs. The assessment round had 50 questions based on Python and OOPS, and the technical interviewer asked questions related to projects, OOPS, and Python. I was rejected in the interview because they wanted expertise in Machine Learning and Data Science.

Why selected/rejected for the role?

The interviewer asked me to solve a coding question, but I was not able to solve that question in the given time. I was rejected in the Interview round. But rejection is a part of life. It gives the motivation to be successful.

Asked in companies

You are given an array/list 'ARR' consisting of N integers, which contains elements only in the range 0 to N - 1. Some of the elements may be repeated in 'ARR'. Your task is to find all such duplicate elements.

Note:

1. All the elements are in the range 0 to N - 1.
2. The elements may not be in sorted order.
3. You can return the duplicate elements in any order.
4. If there are no duplicates present then return an empty array.

Asked in companies

You are given an integer array 'A' of size 'N', sorted in non-decreasing order. You are also given an integer 'target'. Your task is to write a function to search for 'target' in the array 'A'. If it exists, return its index in 0-based indexing. If 'target' is not present in the array 'A', return -1.

Note:

You must write an algorithm whose time complexity is O(LogN)

Problem approach

Compare x with the middle element.
If x matches the middle element, return the mid index.
Otherwise, if x is greater than the middle element, then x can only lie in the right half of the subarray after the middle element. So, recur for the right half.
Otherwise, if x is smaller, recur for the left half.
