Candidates describe Vonage software engineer interviews as a mix of coding, troubleshooting and architecture conversations, and the reports differ by role and level. Prepare for the specific team as well as for general algorithms.
One Software Engineer III candidate who received an offer describes a phone screen with the Director of Engineering. It moved from background questions into rapid-fire troubleshooting such as SQL query optimization. An in-person, one-hour coding exam followed. It combined a sorting problem with object-oriented design. The same day, that candidate met people from development, QA and architecture. Those conversations covered event-driven architecture and message queues versus caching.
A different Software Engineer candidate, who did not get an offer, describes three to four rounds, some remote and some in person. The rounds included LeetCode-style coding of varying difficulty, a conceptual question on how containers work, and questions on Kafka, CI/CD and API testing. That candidate was told the role was SRE and later felt it leaned toward DevOps. They also felt the team wanted deeper domain expertise than the recruiter had described. Ask the recruiter which team and technical depth the role targets.
The reports are few, so confirm the format with your recruiter.

Synthesized from candidate reports. Individual experiences may vary.
Candidates report an initial call with HR or a hiring leader that covers recent work and what the team is looking for in the role. One Software Engineer III candidate says the call was with the Director of Engineering. It typically pays to ask which team and technical depth the role targets.
One candidate reports a conversational start that turned into fast technical troubleshooting questions, including SQL query optimization. Expect questions that depend on the team, and be ready to explain your reasoning aloud. Another candidate, in a DevOps-leaning role, was asked about containers, Kafka, CI/CD and API testing across their rounds.
One candidate reports an in-person, one-hour coding exam in a huddle room with a development manager. The task was a sorting problem with unusual constraints that combined data structures and algorithms with object-oriented design. Another candidate reports LeetCode-style problems of varying difficulty. Practice both kinds of problem.
The offer-receiving Software Engineer III candidate reports back-to-back discussions the same day with development, QA and architecture staff. They covered event-driven architecture and message queues versus caching. Candidates may be asked to discuss trade-offs rather than write code, so prepare to reason about system design.
