Blu Cocoon Digital interview questions

I was previously a java full stack developer and they were looking for a mean stack developer. Although I have not worked in any of the technologies in the mean stack before, they selected me based on my understanding of logic and programming. Hence I came to conclusion that they were looking the IQ with that someone can learn the skill.
