The interviewers were not friendly. In one of the interviews, the interviewer was very arrogant and did not clarify the questions properly. After starting to discuss my approach to the question, he asked too many unnecessary cross-questions and did not let me proceed to code.

Even after coding the solutions to the problems properly, I was not sure why I was rejected. Instead, some of my friends who were stuck in standard questions in one round were selected.

Gender Bias: A lot of preference was given to female candidates. Most of the selected candidates were female.

Given a string and a pattern consisting of 'a's and 'b's, check whether the string follows the pattern. For example, the string "catcatdogcatcat" follows the pattern "aabaa" by substituting "a" as "cat" and "b" as "dog".

Whereas the string "catdogcatcat" does not follow the pattern "aabaa", regardless of what is substituted for "a" and "b".
