PartySlate Software Engineer Interview Guide

Candidates who interviewed for software engineering roles at PartySlate describe a process that starts lightly and then gets heavy. Early stages were a technical or phone screen and a recruiter or HR conversation. One candidate was asked about motivation for joining and projects, and another was asked about willingness to be on-site five days a week during onboarding.

The final stage is where the reports center. A new-grad candidate described a Superday of four back-to-back interviews over four hours, three of them coding problems at LeetCode medium to hard level and one behavioral. Another candidate described a virtual onsite of three technical interviews in a row. A third described several medium data structures and algorithms questions from different interviewers. Taken together, the reports suggest preparing for several coding sessions in one day rather than a single deep problem.

Format quirks stood out. One candidate said an interviewer gave almost no interaction during a long, complex question. Another was told they could ask for feedback but not clarifying questions, which made edge cases harder to catch. An intern applicant faced a 45-minute live CodePair problem about building a target string from letters in other words. One onsite candidate also reported database relationship questions and UI testing scenarios such as login flows, so it is worth reviewing schema reasoning too.

Practice solving mediums without prompts from the interviewer and say your assumptions out loud. All four reports ended in rejection, so treat this as a small sample.
