- Q1. The interview was about js basics
- Q2. What are promises
- Ans.
Promises are objects representing the eventual completion or failure of an asynchronous operation.
Promises are used to handle asynchronous operations in JavaScript.
They can be in one of three states: pending, fulfilled, or rejected.
Promises can be chained together using .then() method.
They help avoid callback hell and make code more readable.
Example: Fetching data from an API returns a promise that resolves with the da...
- Q3. What is async and await
- Ans.
Async and await are keywords in JavaScript used to work with asynchronous code.
Async is used to define a function as asynchronous, allowing it to run in the background without blocking the main thread.
Await is used to pause the execution of an async function until a Promise is settled, and then to resume the function execution.
Async/await is a more readable and cleaner way to write asynchronous code compared to using c...
- Q4. What is callback hell
- Ans.
Callback hell is a situation in asynchronous programming where multiple nested callbacks make the code hard to read and maintain.

- Q2. What would you do if you were given 1 lakh and were told to jump off the first floor? 5 lakh for the 2nd floor? 10 for the 3rd floor?
- Ans.
I would not jump off any floor for any amount of money as it is a dangerous and foolish act.
I would politely decline the offer and explain that my safety and well-being are more important than any amount of money.
Jumping off any floor, regardless of the amount of money offered, is a dangerous and potentially life-threatening act.
I would suggest finding a safer and more productive way to earn money.
I would also question...
- Q3. I give you 5 lakhs right now. Go and kiss the girl standing outside. Will you take the risk?
- Q4. Calculate 12*92 within 15 seconds (without the pen of course)
- Ans.
Answer: 1104
Use multiplication rules to simplify calculation
Break down numbers into smaller parts
Use mental math techniques like rounding and estimation
- Q5. 657*53 within 15 seconds (again without the pen)
- Ans.
To calculate 657 multiplied by 53, we can break it down using distributive property for quick mental math.
Break down 657 as 600 + 50 + 7.
Calculate 600 * 53 = 31800.
Calculate 50 * 53 = 2650.
Calculate 7 * 53 = 371.
Add all the results: 31800 + 2650 + 371 = 34801.
- Q6. The interviewer asked me the length of the room. I said that it was around 18 feet. He asked me to convince him of the same

Interview Preparation Tips
Experience: Two tests completely based on mathematical and logical aptitude and Interviews.
Top 10 rankers of Trade Mogul competition(Trading competition conducted by Future First) are directly called for interview.
Total Questions: 2
Round: Test
Experience: Their sole purpose was to know whether you are capable of handling mathematical calculations easily and quickly. You just need to practice lots of multiplication, division and other simple stuff so that you become quick during the test.
Duration: 30 minutes
Round: HR Interview
Experience: - Choose between Mahatma Gandhi and Subhash Chandra Bose. I personally, would advise you to go for Mahatma Gandhi. If you go for Bose, they will reject you saying that you have a violent side to your personality which of course is not good for them.- What would you do if you were given 1 lakh and were told to jump off the first floor? 5 lakh for the 2nd floor? 10 for the 3rd floor?
Assess the risk in every situation and then using your reasoning, give the answer. I answered that for the amount of money involved i would jump off the 1st and 2nd floors but not the 3rd floor. At maximum I would break my bones or suffer a few fractures which is good enough for the money.
-I give you 5 lakhs right now. Go and kiss the girl standing outside. Will you take the risk?
I said yes I will. She will slap me on the face or maybe get a complaint registered against me with the Dean. It will be a fair deal for the money involved.
-I said, “Sir, my height is about 6 feet. So if I lie down 3 times along the length that should be enough reason for you to get convinced”. So I lied down on the floor along the length of the room thrice.The HR interview was a very different experience for me. I felt that they were looking for a guy who would fit best in their culture and has the ability not only to take risks but also assess it and mitigate it. Besides this they also asked me some HR questions like why should we hire you, what are your goals and why are you suitable for the company. There were few other HR questions as well which were not so different form the regular ones.Overall it was a very good interview experience. They were looking for people who can take risks and were not hesitant to take an initiative and then back their decision with sound thought process.
