Journey
I started my coding journey in the middle of my third year. I first learned the basic data structures and then solved basic algorithmic questions. After grasping the basics of algorithms, I started participating in contests on online coding platforms. After being rejected by some big MNCs, I was selected as a software engineer at Radisys.
Application story
I applied to Radisys through an on-campus recruitment drive. The application process was rigorous but rewarding. It started with the first coding round, where we were given two basic coding questions to solve within a given time limit. Additionally, the round included questions on DBMS, OS, networking, and some aptitude questions. Out of the numerous applicants, only 10 students, including myself, were shortlisted to proceed to the next stage. The next step in the interview process was the interview round. This round was conducted to assess our technical skills and problem-solving abilities in-depth. The interviewer asked me to explain my coding solutions from the previous round, focusing on my thought process, the logic behind the code, and any optimizations I had implemented. Moreover, I faced additional technical questions to evaluate my understanding of fundamental programming concepts. It was an engaging and challenging interview experience. Following the technical interview, I advanced to the final round, which was the HR round. This round aimed to evaluate my cultural fit within the company and my overall suitability for the role. We discussed my career goals, past experiences, and my motivation for joining Radisys. The HR round provided a platform for both parties to assess compatibility and ensure a good match. I am delighted to share that after successfully completing all the rounds, I, along with five other candidates, received an offer from Radisys. The entire process was well-structured, and I am excited to join the company's team. Radisys stood out to me as a dynamic and innovative organization, and I look forward to contributing to its success.
Why selected/rejected for the role?
They were evaluated based on a combination of technical expertise, strong communication skills, and cultural fit with the company's values and work environment, and they found me to be a standout candidate for the role, which led to my selection for this company.

Design a data structure that stores a mapping of a key to a given value and supports the following operations in constant time.

1. INSERT(key, value): Inserts an integer value to the data structure against a string type key if not already present. If already present, it updates the value of the key with the new one. This function will not return anything.

2. DELETE(key): Removes the key from the data structure if present. It doesn't return anything.

3. SEARCH(key): It searches for the key in the data structure. In case it is present, return true. Otherwise, return false.

4. GET(key): It returns the integer value stored against the given key. If the key is not present, return -1. 

5. GET_SIZE(): It returns an integer value denoting the size of the data structure. 

6. IS_EMPTY(): It returns a boolean value, denoting whether the data structure is empty or not. 
Note :
1. Key is always a string value.
2. Value can never be -1.
Operations Performed :
First(Denoted by integer value 1):  Insertion to the Data Structure. It is done in a pair of (key, value).

Second(Denoted by integer value 2):  Deletion of a key from the Data Structure.

Third(Denoted by integer value 3): Search a given key in the Data Structure.

Fourth(Denoted by integer value 4): Retrieve the value for a given key from the Data Structure.

Fifth(Denoted by integer value 5): Retrieve the size of the Data Structure.

Sixth(Denoted by integer value 6): Retrieve whether the Data Structure is empty or not.
