Interview preparation journey

Journey

My journey to where I am today has been very straightforward. I started learning coding concepts from YouTube, but it did not satisfy me. So, I purchased some online courses from Coding Ninjas. I learned DSA from the Coding Ninjas course, and it was great. I also learned the skills used in Development from an online course.

Application story

Urban Ladder came to our college to hire fresher candidates for the post of SDE-1 and Interns. As I was in my 3rd year, I was desperate to get a placement, and the preparations were already underway. I took part in this hiring drive, and finally, I got placed.

Why selected/rejected for the role?

I was selected because I was able to build the optimal solution for the coding questions asked in the interviews. I also practiced good communication skills, and thankfully, I was able to get over my nervousness and confidently pass the interview rounds.

Preparation

Duration: 3 Months

Topics: Data Structures and Algorithms, Database Management System, Operating System, Networking, Aptitude, revised each and every project on my CV well

Tip

Tip 1: Try to be who you actually are in interviews, and don’t try to be over-smart in front of the interviewer, as they know more than you. That’s why they are taking your interview.
Tip 2: Prepare Data Structures and Algorithms. Also, do prepare for theoretical subjects like Database Management Systems and Object-Oriented Programming, as they are part of many interview questions.
Tip 3: I prepared these through the Coding Ninjas notes, which were terrific and easy to understand and covered almost every topic.

Application process

Where: Campus

Eligibility: 6 CGPA

Resume tip

Tip 1: Focus on the Key projects(Major ones), and key courses(Courses like Data Structures and Algorithms)

Tip 2: Just keep applying, off-campus sometimes takes time.

Coding problem2

This round consisted of two coding questions. One was related to binary tree and other was of circular linked list.

1. Search In BST

Asked in companies

There is a Binary Search Tree (BST) consisting of ‘N’ nodes. Each node of this BST has some integer data.

You are given the root node of this BST, and an integer ‘X’. Return true if there is a node in BST having data equal to ‘X’, otherwise return false.

A binary search tree (BST) is a binary tree data structure that has the following properties:

1. The left subtree of a node contains only nodes with data less than the node’s data.

2. The right subtree of a node contains only nodes with data greater than the node’s data.

3. The left and right subtrees must also be binary search trees.

Note:

It is guaranteed that all nodes have distinct data.

2. Deletion in Circular Linked List

Easy

30m average time

0/40

Asked in companies

You are given a Circular Linked List of integers, and an integer, 'key'.

You have to write a function that finds the given key in the list and deletes it. If no such key is present, then the list remains unchanged.

For Example :

This is a visualization of the Circular Linked List, represented by:
1 2 3 4 5 -1

Note :

The Circular Linked List before/after deletion may happen to be empty. In that case, only print -1.

All integers in the list are unique.

HR Round

Duration40 Minutes

Interview date4 Oct 2022

Coding problem2

1. Basic HR Question

Tell me in brief about your projects that you have mentioned in the resume.

Problem approach

I have two projects mentioned in my resume, I started explaining the first one by giving its introduction that is what it does, main objective and scope of the project. Then I explained to him tech stack which was used in the project . Then he asked me to make a flow diagram of the project , which I made on paper and he was satisfied with my answers.
Tips : Prepare for the technologies that you have used in your projects as the interviewer will definitely ask on it.

2. Basic HR Question

Where did you live and tell me your interest areas?
Are you happy with the salary breakup?

Problem approach

Tip 1 : I simply told him everything related to my interests, and always try to speak the truth as most of the time if you are lying, the interviewer will catch that.
Tip 2 : I said “ yes ” because the salary was one of the part through which I got attracted to this company.
