Preguntas de entrevista [1]
Pregunta 1
Asked about experience in previous company, roles and responsibilities
It was 1 hour round with more focus on skills, experience; specially core java and managerial type questions. Interviewer was more interested in leetcode type problem and solution. It was like some exam, not a two way discussion.
