Kandhan Knitss Industrial Engineer Interview Questions and Answers for Freshers

Discussion on the changes in tecehnology

Test followed by the questions and scenario based questions

There were 2 DSA questions that we had to solve on HackerRank. One of them was a medium dynamic programming question - minimum insertions required to make a string palindrome. The other was a fairly easy question that required knowledge of permutations and combinations. We just had to figure out a maths formula given the situation.
1st round also involved a logical game that we had to play. We were scored based on coding + game and shortlisted for next round.

An interviewer joined me on zoom meet and sent a HackerRank link to a question. It was a medium dynamic programming/backtracking question. I solved it but only half the test cases ran while others threw TLE as my recursive code took exponential time.

Q1. Explain what happens after you search a url on your browser. (Had to explain the whole DNS working)
Ans. 
Searching a URL triggers a series of steps involving DNS resolution, server communication, and content rendering in the browser.
• 1. User enters a URL in the browser's address bar.

• 2. The browser checks its cache for the IP address associated with the URL.

• 3. If not found, the browser queries a DNS resolver to resolve the domain name.

• 4. The DNS resolver checks its cache; if not found, it queries root DNS servers.

• 5. The roo...read more

Q5. Asked about the usefulness of OOPS.
Ans. 
OOP enhances code reusability, maintainability, and organization through encapsulation, inheritance, and polymorphism.
• Encapsulation: Bundles data and methods, e.g., a 'Car' class with properties like 'speed' and methods like 'accelerate()'.

• Inheritance: Allows new classes to inherit properties from existing ones, e.g., 'ElectricCar' inherits from 'Car'.

• Polymorphism: Enables methods to do different things based on the ob...read more

Q6. Asked how Java code compiles/runs(had to explain about creation of class file, JVM etc)
Ans. 
Java code compiles into bytecode, which the JVM executes, enabling platform-independent execution.
• Java source code (.java) is written by the developer.

• The Java compiler (javac) converts .java files into bytecode (.class files).

• Bytecode is platform-independent and can run on any system with a JVM.

• The Java Virtual Machine (JVM) interprets or compiles bytecode into machine code for execution.

• JVM manages memory and provide...read more
