Round 3: Technical + Cultural Fit Interview

1. Introduction (4 min) : Interviwer's and then mine.

2. Coding problem (1):

a) Given a string 's' and a string 't'; find the smallest substring in 's' that contains 't' as a subsequence.

Example:

Input: s = "amazonindia", t = "main"
Output: mazonin
Explaination: "mazonin" is smallest substring from striing 's' that contains all the letters of string 't'- 'm', 'a', 'i', 'n'.

Summary:
Solved the question, it took half an hour to give the approach and code. Also explained a sliding window based optimised approach but didn't code that completely.

Problem Link: Minimum Window Substring

This section began with a thorough discussion of my internships, including :

* What were my day-to-day responsibilites in the internships?
* What technologies did I work with and some basic questions around them, like why prefer one framework over another, etc.?
* Any highlights during internship period such as accomplishents or learnings?

Then came the Amazon's well known Behavioural Questions based on their Peculiar Leadership Principles. They also do cross-questioning in this section. Mine were based on the following leadership principles:

* Customer Obsession
* Bias for Action 

Synopsis:

Solved the given coding problem. The interviewer was pleasant, had some interactive discussions around internships and leadership principles. Rembered to incorporate STAR (Situation-Task-Action-Result) methodolgy in my answers. So, all-in-all a decent interview experience.
