Interview Preparation Tips
1. The position you have applied for can help you assess the questions in most of the times .
For example
- In my case I applied for a systems Engineer position which requires a basic knowledge of programming and good communication skills .
- In case If you have applied for a DSA of power programmer interviewer would definitely test your deeper understanding in programming and any other new Technologies
2. Be Prepared for an interview before the exam itself . We can expect few HR questions even before entering the interview panel room . So donot ignore such sure shot questions like
- self intro
- are you willing to relocate ( obviously Yes in many cases)
- shift related
- where do you see yourself after 5/10years
- strengths and weakness
- how are you handling your weakness
3. Never answer more than what's required .Be precise and crisp
If you don't know the ans just let the interviewer know that you are unaware of the topic and share well-known topics of yours

- Q1. How Quick sort works
- Ans.
Quick sort is a divide-and-conquer algorithm that sorts an array by selecting a pivot element and partitioning the array around the pivot.
Select a pivot element from the array
Partition the array into two sub-arrays: elements less than the pivot and elements greater than the pivot
Recursively apply the same process to the sub-arrays
Combine the sorted sub-arrays to get the final sorted array
- Q2. How Merge sort works
- Ans.
Merge sort is a divide and conquer algorithm that divides the input array into two halves, sorts them separately, and then merges them.
Divide the array into two halves
Recursively sort each half
Merge the sorted halves back together
- Q3. Writecodefor binary search
- Ans.
Binary search is a divide and conquer algorithm that efficiently finds the target value within a sorted array.
Start by defining the low and high indices of the array.
Calculate the mid index as (low + high) / 2.
Compare the target value with the value at the mid index and adjust the low and high indices accordingly.
Repeat the process until the target value is found or the low index surpasses the high index.
