I have two interviews this week for a Junior Full-Stack Developer position at two different companies.
The first company were good enough to let me know that the interview will be informal, nothing heavy, they will ask me mostly questions about my aspirations and tech path. This kinda made me feel more relaxed because I was studying really hard for the tech part.
The second company will probably give me tech test. The tech stack is slightly different in both companies, but they all share a common core.
How do I prepare for both of these interviews? Should I study and be prepared only for the technologies that are similar to both companies, or should I push myself to understand a little bit each technology the company uses?
