Interview preparation journey

Journey
It all started when I got admission to the Devi Ahilya Vishwavidyalaya IIPS department for the 5-year MCA Integrated course. We learned basic languages like C, C++, and Java, along with other computer fundamentals. As placements approached, I started working on DSA, Operating Systems, DBMS, and OOP concepts in Java. I practiced interview questions on coding platforms, which helped me earn the skills required to crack the interview and get an offer.
Application story
As it was an on-campus recruitment process, we received the notification about this company through our placement cell group and applied for it. The process mainly consisted of three rounds: a written test, a technical interview, and an HR interview.
Why selected/rejected for the role?
SELECTED. I learned that we need to be clear about our goals and prepare accordingly. Start by solving easier and smaller problems, then progress to more complex ones. It's also important to have a strong understanding of current technology requirements.

You are provided with the two strings named X and Y respectively. Y has its own specific order and has no repeating characters. Your task is to arrange the characters of the first string i.e. X in such a way that the order of characters in X is exactly the same as in Y, which means if ‘d’ occurs after ‘c’ in Y then it should also occur after ‘c’ in X ( obviously if X has ‘d’ and ‘c’ as characters in it ). All you have to do is, convert string X in the specific order with respect to string Y.

Note :

Both the strings have only lowercase English alphabets. 
There may be more than one correct solution, you have to return any one of the possible solutions.
