Interview preparation tips for other job seekers - Don't apply for this company. Main reason is strictly 5 days work from office. Hr are so much incompetent in terms of explaining the process as well as job role. Delayed response and rude behavior.bo feedback and not even shared the outcome of interview. Has to ask multiple times to receive response. Seems engineering department isn't capable enough to decide what they actually want from candidate and what should be the outcome of questions asked.
