There was no HR interview.
When you apply they send you a task and you have a week to submit your solution. The interview process took too long, they replied a month after I submitted it, and we scheduled the interview. The interview is mostly questions about the solution and the approach you have taken. It is to see how well you know OOP. After that, I was asked to do another task and again I had a week to submit. The contacted me like two weeks after that to have the second interview. The second was mostly about the technology used and how would you solve certain problems and scenarios.
