HR contacted me via LinkedIn and we discussed various aspects of my resume. The interview process consisted of five rounds:
Hiring manager round
Technical coding round
Advanced technical coding round
Design round
Managerial round (behavioral)
The first coding round was straightforward, involving a string-based problem and a random number generator. The interviewer was less experienced, but it was a pleasant conversation, and I cleared it easily.
In the next coding round, conducted by an interviewer from Argentina, I was asked to solve an optimization stack-based problem and write production-grade code. He was impressed with my solution, and I cleared both technical rounds on the same day without any preparation.
The design round involved a simple design question. I proposed multiple approaches, leveraging my expertise in design. However, the interviewer seemed to have limited knowledge of system design and couldn’t fully grasp highly scalable and distributed design concepts. I later heard that his feedback was not very positive. It seems Dialpad lacks a specialized interviewer for design.
The final round was scheduled with an onsite interviewer from Canada. After a couple of reschedules, the interviewer finally became available but arrived 10 minutes late. The interview, held around midnight, was tough. He mostly asked about my reasons for changing jobs and no technical questions, appearing disinterested.
Ultimately, I received negative feedback. However, a few days later, I received an offer from another company. My advice is to avoid wasting your valuable time and ensure you engage with serious companies.
