eQ Technologic Interview Experience 2021 | On Campus (Virtual)

The eQ Technologic visited our campus in July 2021 for the placements. The process was consisted of 4 rounds –Online TestInterview Round 1Interview Round 2Interview Round 3 (Final Round)The complete process was as follows:Online Test: The AMCAT Test was conducted. There were 14 Logical Reasoning questions to solve in 14 minutes in the module 1. The questions were on finding missing/next term in the sequence, odd-one-out, relationships, etc. In the module 2, two coding questions were given to solve in 60 minutes. The coding questions were –Finding the distinct permutations of the given list of numbers.Print the following pattern if value of N and Start number is given.Example:
N = 4, Start = 3,
then output should be –
Output:
3
44
555
6666
6666
555
44
3The Online test was easy.Technical Round 1: The round last for 60 minutes. The questions were on core concepts like OS, Data Structures, SQL, DBMS, etc. The round started with the question “Tell me about yourself”. Questions are –Which is your favorite subject in engineering? Why you like that subject? (I told that OS is my favorite subject. So he asked me some questions related to that.)What is core in CPU?Which CPU scheduling algorithms are there? Which is the best one?Which are the types of queues used in CPU scheduling?What is deadlock? How deadlock occurs?What are techniques used to prevent deadlock? Which technique is more useful and why?What are the different data structures do you know? Their practical uses.What is difference between SQL and NoSQL databases? Have you used these databases? Which is the fast in accessing the data?How to make NoSQL databases fast in order to increase efficiency when we have unstructured data stored in the database?What is normalization? It’s importance and how to check whether database is normalized or not?Then, he gave me 3 tables and asked some of the SQL queries to write down. He also asked that whether these tables are normalized or not.He asked me to write the code for “Check whether the given string is Palindrome using Stack” and “Level Order Binary Tree Traversal“.Lastly, he asked me a small puzzle similar to this.Technical Round 2: This round also last for 60 minutes. The interviewer asked me about my previous round and extended the questions based on previous round. This round majorly focused on deep understanding of concepts.How was your previous round?Questions on types of memory in the OS.What is process in OS?Then he asked some of questions on OOPs. What is difference between Procedural programming and Objected Oriented Programming? Have you used OOPs concepts in your academics and have you implemented those?What is data binding? What is encapsulation? Give me real case example where you will use encapsulation.Which programming languages do you know and which is you use most? I told that I use Java mostly so he asked me about that.What is abstraction? What is interface in java? Difference between abstraction and interface?What is need of interface if we have abstraction?How did you use interface in your projects? I told that I have implemented abstraction so he switched on abstraction and asked me to explain it’s implementation.What is thread in java? It’s significance? (I told about java threads in answer of above question).He gave me a use case where I have to manage logged in users in the system using threads and I have to maintain the threshold limit of logged in users. How will I implement and use thread concept over here?He asked me two write the code on how to check the numbers are from the Fibonacci Series if input is the list of numbers? Then he asked me to optimize the solution, asked me time and space complexities of my approach.Then he asked me about nested SQL queries on the tables given in the round 1 (As he asked me what were questions on DBMS in round 1).Final Round (Round 3): This round last for 30 minutes questions and answers + 45 minutes to write the code.Tell me about yourself (Constraints were not to tell family background, about family and friends, and about profession).What are your hobbies and achievements in those?How would rate yourself in C, C++, Java, SQL, and other technologies you know on the scale of 1-10?The he give me question similar to this and asked to write the code in 45 minutes.All the interviews were easy. I was selected. I would like to thanks GeeksforGeeks because it helped me to prepare for this.
