I am Ph.D. student in India working in computer science. I will be graduating soon. I have two options: 1) post-doc 2) join a "tier 2 institute" (i.e., an institution ranked between #11 and #20 in India) as a faculty. I don't have sufficient publications to join a tier 1 institute.

I am inclined to go for a post-doc because I want to improve the quality of my research. Many people are suggesting that I join tier 2 institute and then keep working. My research field (computational mathematics) is such that if I have to work alone then I can only publish one paper per year, but in a collaboration I can publish with more speed. Some people told me postdoc will impact you badly if you do not publish enough. I don't know what to do but I want to pursue my carrier in research.

My question is: what are the pros/cons of doing the post-doc vs. taking a tier-2 faculty position?
