PayPal Machine Learning Engineer interview questions

The interview is around 1 hour and 40 minutes and there're two engineers hosting the interview for you. The process goes like this : is self introduction (In Chinese and English) -> details of the projects listed in you resume (In Chinese or English as you like) -> code interview (leetcode median, choose any program language as you like) -> ask the questions you're interested.

I recently went through PayPal's interview process for an ML role, which typically consists of four rounds: 1. Coding + Machine Learning 2. Coding + Machine Learning 3. In-depth Machine Learning 4. Machine Learning Business Case Study In my case, I had an additional round focused on a combination of Machine Learning and Coding, bringing the total to five interviews over the span of three weeks. While the technical depth of the interviews was commendable and challenged my expertise, the experience post-interviews has left much to be desired. It's been a couple of weeks since my last round, and despite following up, I haven’t received any feedback or updates on the outcome. This lack of communication raises concerns about the level of professionalism and transparency within the hiring process. Based on this experience, I would hesitate to apply to PayPal again, and I would advise others to be mindful of the potential communication gaps in their recruitment process.
