Capgemini Angular Developer interview questions

Was an online interview. I thought it went well. Not sure why I didn't get selected. Out of the 10-15 questions asked, I didn't know the answers to two questions and those were not even that relevant. (eg: how would you translate angular application to another language.) Obviously, I've not worked on such a requirement and I honestly didn't know the answer for that. If I was judged only for this wrong answer, then I have to say it's a pretty unfair interview process
