2nd Question:- Given an alien language dictionary where the words are sorted, we need to figure out the list and order of the alphabets for that language.

Round 2 (Technical)
1st Question:- They gave me a question for implementing wildcard pattern matcher. He specifically mentioned that he wanted a clean and optimized code.

2nd Question:- Given a dictionary containing some words, and a start word and end word, you need to find the minimum number of conversion needed to convert start word to end word with the following restrictions:-
1. Each intermediate word must be in the dictionary
2. You can change only one character in the word to convert to another word.

Example If You are given start word as ‘SAT’ and end word as ‘PAN
