Interview Questions

Exponent - "This is a Fermi problem — an estimation or approximation problem with limited information and back-of-the-envelope calculations. There's no right answer: interviewers want to understand how you think and how well you can explain your reasoning, rather than what you already know. Recall the formula for Fermi problems: Ask clarifying questions Catalog what you know Make equation(s) Think about edge cases to add to equation **Breakdown components of your equat"See full answer

It is likely the servers were storing session data on the server themselves (in-memory), and thus when user makes a request, the load balancer routes this to a different server than the one they started with, that second server may not recognise the user's session.

And also I will keep some buffer as well. I will ensure I communicate to the stakeh"See full answer

Takashi M. - "Designing a Pseudo Random Number Generator (PRNG) involves creating an algorithm that generates a sequence of numbers that appear random while being deterministic, meaning that the same sequence can be reproduced given the same initial conditions. Here's a basic outline of how you could design a PRNG: Define the seed: The PRNG algorithm requires a seed value to initialize the generator. The seed can be any value, such as a number provided by the user or obtained from system data like the curr"See full answer

Soundharya S. - "Designing a smart fridge is something we can compare with designing our smart phone, obviously which is not as handy as our mobile phones. I can design in such a way that it is operated through our mobile phone. for ex, if we are out of town instead of worrying about the condition of the items in the fridge we can stay close with just one click away, while coming to product installation then I would say instead of taking a lot of time in searching the items, showcase a display where a list of it"See full answer
