Dialpad Staff Software Engineer interview questions

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.

Technical phone interview followed by a virtual onsite. Onsite interview had 2 rounds of coding + 1 round of system design + 1 round of talking to the manager. One of the best interviews I've ever had. Nicest people on the panel. I got the answer to the interviews one day after doing the onsite. One thing I wanna point out is that all 3 technical questions (phone and onsite) were heavily algorithm based and were not practical. This is not either a positive or negative point but I personally prefer questions that show your skills you have obtained via experience, not doing leetcode questions.
