Ecoult interview questions

It was a little difficult to find their office. Several offices at floor 4 and one at floor 1 and the interview happened at floor 1. It seems that they don't have a formal front desk. I entered one floor 4 office and knocked the door to let people know I came for interview. A very nice man leaded me to the right place and helped me confirmed there was a interview for me (sounds weird huh? They seems forgot there was an interview lol. But I don't blame them because they are really nice and I don't grab time). The nice guy is a system engineer. The interview was about 1 hour. One team with 3 team members all participated the interview. One is leader and one is front end (Angular2+) and another one might be full stack? I can't remember. The interview started right after another team finished meeting. Team leader introduced his team and why they use node js. Every one was very nice and I personally think we had a good conversation about my skills. They want a person have experience for Angular4, Nodejs, Python, Linux.
