Hi, I’m David. I’m a software engineer living in usa. I am a fan of education, programming, and web development. I’m also interested in fashion and cats. You can read my articles with a click on the button above.

At the same time, I am also one of the initiators of OAassist. The following is an introduction to our team.

OAassist has been providing technical job interview assistance services to interview candidates of American technology companies for more than 8 years, especially for VO interview assistance and OA interview proxy. The team is good at interview services and simulations for core programming positions such as SDE, DS, MLE, AS, etc. We have helped more than 1000+ candidates successfully obtain offers from North American technology giants such as FAANG.

The service team members are all doctoral students in computer science from the top 10 universities in North America and the UK. Our interview assistance tutors have all worked in R&D work in companies such as Google, Amazon, Apple, and Microsoft. At the same time, they are also interviewers and question setters in the core departments of these companies, and can provide students with high-quality interview services.
