Sony Software Engineer Internship interview questions

One behavioral interview and two technical interviews. The behavioral interview was very straightforward. The person form HR didn't specify that my last two interviews were technical even though I asked twice via email. Interviewers were friendly and helpful.

First introduce my self. Then ask why choose Sony. Then introduce the department I applied. Then give 2 assignments that is from Leetcode. Both of all are about palindrome. Although I passed the test I didn't get offer.
