LeetCode Problems Asked At FAANG Interviews - Part 1

The world has seen a number of job cuts worldwide. Some of the software engineering workforce has quit their jobs by their own will.

In such trying times when all economies are dwindling, it is the chance for the workforce to instead of giving up, pause and introspect on their ideal next workplace, and give their best to come out of the lockdown with flying colours.

I am a Software Engineer myself and with the aim of providing a not so unconventional path to help other software engineers reach their similar goals, in the last 2-3 weeks of my free time I audited the frequently asked problems at one of the big gigs in the software industry, particularly focussing on Amazon, the 'A' of "FAANG"(Facebook, Amazon, Apple, Netflix and Google).

In this blogpost I have collated some of those problems asked at Amazon, which will be useful for anyone preparing for interviews at Amazon and also someone who is trying to just get started with interviewing in general.

Amazon Interview Questions solved and audited by me:

1. First Unique Character in a String
2. Single Number
3. Power of Two
4. Robot Return to Origin
5. Missing Number
6. Best Time to Buy and Sell Stock II
7. Path Sum
8. Letter Combinations of a phone
9. Remove Element
10. Climbing Stairs
11. Lowest Common Ancestor of BST
12. Jewels and Stones
13. Container with most water
14. First unique character in a string
15. Flood Fill
16. Reverse Linked List - Try Iterative and Recursive both
17. Most Common Word
18. Unique Email Addresses

I would encourage all those who are getting set for preparing them for interviews to go through these problems by their own and feel free to ask their questions and share their doubts with me to keep this discussion open-ended and the Let's Code_ problem solving community alive! As you would have seen, the problems asked at Amazon are fairly simple and most come under the easy category of problems on LeetCode so they are good for starters.

Mock-interviews go a long way to help judge your standing among peers and have helped me many times as well.

I particularly conduct and give interviews on PRAMP (www.pramp.com) an acronym for PRActice Makes Perfect, and if you ever need PRAMP credits to sharpen your skills, feel free to get in touch! Do ping me with your account and I'll be happy to share some with you.

Until then, Happy Coding!!

Lockdown and Upskilling Problem Solving

Being busy has never given anyone a chance to reflect and up-skill themselves.

One of the best things a programmer can do to up-skill their coding capabilities is to work on the Art of Problem Solving and becoming world-class in doing it.

Why not must one utilise the Lockdown period with up-skilling oneself using techniques outlined by veterans like the CCDSAP curriculum which is laid down as a guidance mechanism to gain control over exactly what you want - problem solving using programming!

With the same line of thought in mind, I have restarted my programming practice and I'll document for you, how I go about the curriculum as we progress through this blog!

There are a few other up-skilling sites I keep in touch with like spoj.com, leetcode.com and hackerrank.com and I'll blog about solving problems there as well.

So, Let's Code!!!
