Amazon Developer interview questions

Amazon UK, on the first round of coding, i was being asked something like to build a treee from string, i am tried to impelement the logic but the interviewer was not helpfull

The interview process was intense but fair. Started with an online assessment focusing on data structures and algorithms. Final rounds included two technical interviews and a behavioral one (“Leadership Principles” came up a lot). Interviewers were professional and gave helpful hints when I was stuck. One question involved designing a scalable service for real-time notifications—definitely challenging! Overall, a great experience—fast-paced, but reflective of Amazon’s high standards.
