加拿大多伦多大学Vector institute岗位面试

投了多伦多大学下的AI研究所vector institute的一个machine learning specialist的岗位，类似machine learning engineer吧。然后收到邮件说要给我发Byteboard的OA，
还发了大概流程如下：
Technical Reasoning Exercise (40 min): You will work on a document outlining several different implementation options for a product. You will be tasked with completing the document by choosing an option and answering any questions left by other members of the product team.
Code Implementation Exercise (70 min): Following the technical reasoning exercise, you will implement a few aspects of the product described in Part 1. You will need to navigate a small multi-file codebase and write clean and functional code.

有人面过它家类似岗位吗？知道这具体是啥题目什么题库吗？该往什么方向准备呀？这是考数据结构与算法还是系统设计还是ML system design？或者ML project 建模?。都不知道怎么临时准备。
