Can I attend Fresh H1B interview from different country?

I currently live in India(Indian citizen) and I will be traveling to Germany in August for about 8-9 months on official work.

My question is can I take H1B interview from Germany instead of India.

I am ready to travel back to India and attend the Interview but my only worry is If I don’t get my passport on time(if not within a week), how will I go back to my job at Germany?

You may be able to take H1B interview there. It all depends on the country’s US consulate rules. You need to check with them, if they allow third country nationals stamping. Write to the embassy, you will get to know, if you cannot confirm on their website.
