Myntra

I have applied for Myntra sde internship and waiting for the rounds to start. According to my research the process takes one online assessment (coding + mcqs) followed by 3-4 technical and 1 hr round. The questions were really medium and hard level(like it ranged from strings arrays linked list to bfs dp and what not), any suggestions how to prepare or to expect from those who are acquainted with such interview? Please share:)
