Amazon Software Development Engineer, II interview questions

Received an OA, invited to a virtual full-loop interview (4 rounds, 50 mins each). The experience was disappointing and unprofessional. Most of the interviewers came across as rude and unwelcoming. Two out of the four actually laughed at my explanations during the technical and behavioral discussions, which was shocking and disheartening. This is especially surprising given that I have 5 years of experience developing enterprise applications and have been through numerous interviews before. I understand that interviews are meant to be challenging, but there’s a clear line between assessing a candidate’s skills and being disrespectful. The lack of professionalism from the interviewers has left me questioning the company’s culture and values.
