American Express Interview Question
The first round questions included basic dataframe manipulations, a regex question on writing a pattern to identify specific phrase which could have any number of random words in between (eg. between high and calorie, there could be any number of words upto 4 eg. high word1 calorie, high word1 word2 calorie' etc). This also needed some basic preprocessings like handling unidecode errors, punctuations and numbers in a string. Another question was a probability based descriptive question and a easy question on coding to print numbers between 0 to 100 which were prime.

The dataframe manipulations were basic pandas problems, the regex pattern could be solved by having a pattern like r"high\s((\w+)\s){0,4}calorie". Could not solve the probability one, and prime number one can be found anywhere on internet
