Cognizant GenC Interview Experiences for 2022
Before specifying the Cognizant GenC interview questions, let us understand the interview experience as detailed by candidates who appeared for the GenC profile interview this year.
The whole interview has a total of three rounds:
- Round 1: This is a Cognizant online exam: This is an online assessment round that comprises five parts:
- Part 1: Consists of aptitude, DSA, reasoning based MCQs
- Part 3: Consists of two coding questions (easy, medium), which need to be completed within thirty minutes.
- Part 4: Consists of two coding questions (medium, hard), which need to be completed within forty-five minutes.
- Part 5: Consists of 2 SQL query questions (easy, medium).
- Round 2: This is a technical questions round. The whole round is conducted on a superset platform and is mostly focused on communication and technical skills. The candidate should be proficient in computer science fundamentals such as DBMS, OOPS, OS, and CN and should be able to interact and answer the interviewers clearly. Programming language knowledge is a must. It is not necessary for the applicant to be fluent in all programming languages, but the candidate should have sufficient experience with at least one language, such as Java, C++, or Python. The duration is 30 minutes. The whole round consists of:
- Project-based questions
- Questions related to why choose IT
- Aptitude problems
- OOPs concepts
- Explanation of encapsulation and abstraction
- Writing some easy programs such as “a program to find whether a number is odd or even?” or “a program on the Fibonacci series”.
- Round 3: This is the HR round and the duration of this round is around ten minutes. However, one can never be prepared for the HR interview questions and answers. You can create a list of the most popular HR interview questions and practice answering them. You must have the answers to these questions at your fingertips. Another essential thing to keep in mind while going for an interview is to look and behave confidently. Candidates need to know that there is no need to lie or seem overconfident. Projecting excellent body language makes all the difference. It is generally a document verification round where mark sheets and ID cards are verified along with some general HR questions, such as:
- Tell me something about yourself.
You can begin with your academics, achievements, projects, other interests, and strengths. Also, tell them about your background, hobbies, etc.
- Where do you see yourself in 5 years?
- Why should you be recruited?
- What are some of the things about this role that you enjoy?
- How was your final year project? Tell us the details. What new ideas did you integrate into this project?
Top GenC Interview Questions and Answers
Following are some of Cognizant GenC interview questions that are typically asked by interviewers, along with the answers.
1. What do you understand about Retroactive, Proactive, and Simultaneous Update in the context of DBMS?
- Proactive Updates: These modifications are made to the database before it is put into use in the real-world environment.
- Retroactive Updates: These modifications are applied to a database after the DBMS has been in use in the real-world.
- Simultaneous Updates: These updates are applied to the database at the same time as they become functional in the real-world environment.
2. Explain what is the fill factor in SQL and what is its default value?
The fill factor is the amount of space on each leaf-level page that is filled with data. The lowest unit in a SQL Server is a page, which comprises around eight thousand pages. Based on the size of the row, each page can store more or more than one row. The default value of the Fill Factor is 100, which is the same as the value 0. The SQL Server fills the leaf-level pages of an index with the maximum number of rows it can accomodate, if the Fill Factor is assigned to 0 or 100. Once the fill factor is 100, the page has no or very little empty space.
3. What is index hunting? How does it aid query performance?
Index hunting is the technique of increasing a collection of indexes. It is mainly done as indexes enhance query performance as well as the query processing time. It helps in query performance improvement in the following ways:
- The optimal queries are recommended using the query optimizer.
- To assess the effect, parameters such as query distribution, index, and performance are used.
- Databases are augmented into a small group of problem queries.
4. What are the steps to create, modify and drop a view in SQL.
In SQL, a view is one table that comprises data from other tables. As a result, a view features columns and rows that are similar to those of a real table, and fields from one or more tables.
- In order to create a view:
CREATE VIEW View_Name AS
SELECT Column1, Column2, Column3, ..., ColumnN
- For modifying a view:
CREATE VIEW OR REPLACE View_Name AS
SELECT Column1, Column2, Column3, ..., ColumnN
- For dropping a view:
DROP VIEW View_Name;
5. What factors influence if a detection algorithm is required in a deadlock avoidance system?
This question is one of the very common Cognizant GenC interview questions. Whether a detection algorithm is required depends on how frequently a deadlock can occur when the algorithm is implemented. The other factor is the number of processes that are affected by deadlock if this algorithm is used.
6. Explain how dynamic loading allows for enhanced memory space utilization?
In the dynamic loading technique, a routine is never loaded unless it is called. This strategy is quite effective when managing huge quantities of code, such as error routines that occur occasionally. All the routines are kept in a relocatable load format on the disk. The main program is implemented once it is loaded into memory. When a routine needs to call a different routine, the calling routine verifies if the previous routine has been loaded. If not, the routine is loaded into the memory and the program's address tables are also updated using the relocatable linking loader. The newly loaded routine is then provided with control. In this manner, dynamic loading helps in enhanced memory space utilization.
7. Explain Root Partition in OS?
The root partition is where the Operating System (OS) kernel is available. Various other potentially crucial system files that are mounted during boot time are stored in it too.
8. What is the need for a Virtual File System (VFS)?
Virtual FileSystem Switch or Virtual File System is an abstract layer on top of a more concrete file system.
- VFS is necessary for client applications to access different types of concrete file systems in a reliable manner. For example, a VFS can be utilized to seamlessly access network and local storage devices without the client device identifying the difference.
- It can be utilized to bridge the gap between traditional Mac OS/macOS, Windows, and Unix file systems, enabling applications to access files on those types of local file systems without the requirement to know what type of file system they are dealing with.
- A VFS describes the kernel's interface with a specific file system. As a result, providing support for new file system types is easy.
9. Explain what caching is and how does it work?
Caching is a technique for saving multiple copies of the most frequently used data in a cache or a temporary storage area so that access is easier. It keeps the data in a temporary format for servers, software applications, and web browsers so that users don't have to download information each time they use an application or visit a website.
Cached data works by saving the data in a device's memory to be accessed later. The data is stored in the computer memory, directly right below the Central Processing Unit (CPU). The primary cache level is integrated into a device's microprocessor chip, along with two more secondary cache levels. This data is retained until the content's Time To Live (TTL), which specifies how long it should be cached, expires or the device's hard drive, or disc cache fills up.
10. What is Trapdoor in OS?
Another one of the frequently asked Cognizant GenC interview questions. A trapdoor is a hardware or software mechanism that is used to bypass system controls. It is a malicious software that enables an attacker to gain illegal access to a network or computer system by accepting remote commands. Trap door software monitors a specific User Datagram Protocol (UDP) or Transmission Control Protocol (TCP) port for orders.
Now, that you are aware of Cognizant GenC interview questions, following are some of the Cognizant FAQs:
