I applied online and received a call a couple of days later.

The interviewer seemed to be in a hurry. For someone with only six months of experience, he was asking about back-end React questions during the first interview, which was quite surprising. He seemed taken aback if you didn't know the answer.

The best part was that he was from the design team. He pulled a list of React questions from the internet and was asking them to candidates. He actually mentioned that people didn't know what he was talking about.

Just a recommendation: if you want a full-stack React developer, don't post a job description for a designer background. It's ridiculous!
