The interview was a Level 3 phone interview. The interviewer was a very nice person who presented a lengthy question. Essentially, it involved a 2D array as training data, for example:
[[‘I’, ‘like’, ‘apple’],
[‘You’, ‘like’, ‘orange’],
[‘apple’, ‘orange’, ‘like’]]
The task was to write a function to predict the most likely next string after a given string. The question was a bit ambiguous, requiring continuous clarification and consideration of edge cases. Although I struggled for a while and almost ran out of time, the interviewer seemed quite satisfied. The next day, I received an email from a recruiter saying I had passed. By the way, I want to complain about the recruiter from 
company who didn’t reply to emails and even scheduled the interview at the wrong time (not the time I provided).
This is my first time sharing interview experiences, hoping for a little reward! Thank you!
