Trifacta Software Developer interview questions

I did a one on one phone interview with an engineer and then came onsite to do four interviews with different engineers/managers. Questions were mainly algorithm/data structure based and fairly generalist. I received an offer within a week of interviewing.

The HR calls me and asks behavioral questions for about 15 minutes. I think the intern prefers the applicants to focus on data science, but I do not have machine learning experience. The general process was smooth and happy, but the only problem is my answer to the question about what do you want to focus on. Maybe he thinks that my projects are too broad and he did not find a focus. I will pay attention in the future.
