For lateral roles, the experience starts with an initial recruiter contact followed by an online coding or technical assessment platform evaluation. Subsequent stages include one or two internal Brillio technical interviews focusing on live coding, system design concepts, and stack-specific execution. Depending on the client engagement model for the position, candidates frequently undergo one or two additional technical screening rounds directly with the client's engineering panel before progressing to final managerial and HR discussions.

Campus hiring drives and structured hiring events follow a compressed timeline. These processes generally begin with an extensive Online Assessment (OA) covering technical MCQs, database queries, and algorithmic coding, followed by a Group Discussion (GD) round to assess verbal articulation and teamwork. Qualified candidates then complete one or two face-to-face or virtual technical panels and conclude with an HR evaluation.

The visual timeline above outlines the standard progression across screening, technical evaluation, client alignment, and offer processing. Use this roadmap to structure your preparation time, ensuring you allocate sufficient focus to both internal core technical fundamentals and client-facing communication skills. Note that lateral candidates may encounter additional client rounds, whereas campus candidates will navigate initial group discussion stages.
