- Q1. Node js working in detail
- Ans.
Node.js is a runtime environment that allows you to run JavaScript on the server side.
Node.js is built on Chrome's V8 JavaScript engine.
It uses an event-driven, non-blocking I/O model that makes it lightweight and efficient.
Node.js is commonly used for building server-side applications, APIs, and real-time applications.
It has a large ecosystem of libraries and frameworks, such as Express.js and Socket.io.
- Q2. Timer working in node
- Ans.
In Node.js, timers can be implemented using functions like setTimeout() and setInterval().
Use setTimeout() to execute a function once after a specified delay
Use setInterval() to execute a function repeatedly at a specified interval
Clear a timer using clearTimeout() or clearInterval()
Example: setTimeout(() => { console.log('Timer executed!'); }, 2000);

- Q1. What is the internal implementation of Hashing and what is collision?
- Ans.
Hashing is a technique used to map data to a fixed-size array, collision occurs when two different inputs produce the same hash value.
Hashing involves using a hash function to map data to a fixed-size array.
Collision happens when two different inputs produce the same hash value.
Common techniques to handle collisions include chaining and open addressing.
- Q2. Is time complexity of HashMap always O(1) ?
- Ans.
No, time complexity of HashMap is not always O(1).
Time complexity of HashMap is O(1) on average, but can degrade to O(n) in worst case scenarios.
Worst case scenarios include hash collisions, which can lead to linear probing and degrade performance.
Load factor and capacity of the HashMap can also affect time complexity.
In scenarios where many keys hash to the same index, the time complexity can degrade.

- Q1. How js async working
- Ans.
JavaScript async allows non-blocking code execution by using Promises or async/await syntax.
Async functions return a Promise object.
Promises represent a value that may be available now, in the future, or never.
Async/await syntax simplifies asynchronous code by using keywords async and await.
Callbacks can also be used for handling asynchronous operations.

- Q1. What is gcd? And explain it
- Ans.
gcd stands for greatest common divisor, the largest positive integer that divides two or more numbers without leaving a remainder.
gcd is used to find the largest integer that can evenly divide two or more numbers.
It is commonly used in mathematics and computer science algorithms.
For example, the gcd of 12 and 18 is 6, as 6 is the largest number that can divide both 12 and 18 without leaving a remainder.
- Q2. What is arc and explain it
- Ans.
ARC stands for Automatic Reference Counting, a memory management technique used in programming languages like Objective-C and Swift.
ARC automatically tracks and manages the memory used by objects in a program
It increases the retain count of an object when it is referenced and decreases it when it is no longer needed
ARC helps prevent memory leaks and retain cycles in iOS and macOS development

Interview Preparation Tips
I was interviewed in Feb 2017.
Interview Preparation Tips
Experience: Three questions were given and asked to write programme in any of the language we are strong at.I need not describe much about it as it is available online which I came to know later.I suggest one to do that test once before he/she goes to interview
Tips: Generally question with low marks is easy to solve which indirectly test if you really have done something with programming. Better read all the three questions before you start programming sometimes question with more marks may also be easy,
If you are not able to pass all the test cases don't worry about it try to run all the three atleast for one case with out syntax errors
Duration: 1 hour 30 minutes
Total Questions: 3
Round: Technical Interview
Experience: I don't remember the questions much but , they gave me a form to fill before interview , in which there is section asking for technical skills, be cautious while filling it as questions are going to be from the topics you write there, don't write anything with which you are not confident with. I wrote c, do they made me write programmes.
Tips: Don't worry if they find bugs with your code , accept the mistakes if they give chance fix it. Better take time write the best code you can. They asked me a general puzzle.
Skills: Programming, Logical Puzzles
