Pipe17 Senior Software Engineer interview questions

I got the opportunities by hr. The interviews are planned so quickly in the next working days. There are 2 rounds of interviews. The 1st round is held by 2 interviewers, a backend developer, and a frontend developer. The frontend developer cannot seemingly take the role, and he said javascript is a similar C++ program language. (shocked) The 2nd round is talking with the lead in China focusing on the expected salary, from a product round.
