I had 2 rounds in total, both was online. The 1st round consisted of mainly behavioral questions, and it was automated on a website (no interviewer). The 2nd round was a technical assessment where i had to do a presentation.

Thorough, engaging and comprehensive. For me, it was a multiple step interview with tough questions asked - from written to online recorded interview to case study to actual panel interview.

First HireVue interview quite average. Prepare yourself as you only have 3mins for each question and only 3 tries. It will also include a quick math and similar figure game. You need to react fast to achieve higher level. Final interview very technical. You are given 24hrs to study and prepare a case study on designing a product concept. Final interview mostly was about the design you propose. You must think outside the box. Even if you dont, at least have good reasoning. If you know how competitive Dyson is, then prepare to give a spectacular answer.
