Interview Preparation Tips

Interview preparation tips for other job seekers - It's a good company however, they do not respect employees as much. Throughout the interview process, I felt disposable and disrespected. They kept rescheduling interviews at the last minute, did not display any understanding w.r.t timings for the interview (they asked me to take leaves and remove time for the interview, & then rescheduled them cause of panel unavailability).
Not the culture i was looking for and hence I have let the offer go. However if you're looking for something stable, it's a good company.
