Zoho’s Hiring Process is Completely Biased
Zoho gives priority to Tamil-speaking candidates, and only if there are extra vacancies do they consider people from other states. I cleared all five coding problems, optimized them as requested, and explained my approach clearly. The technical live coding interviewer, Seethu Maria Johnson, even told me that HR would contact me. But instead, I got a rejection email without any explanation.
It feels like Zoho already decides who they want to hire based on regional preference rather than talent. If you're from outside Tamil Nadu, don’t waste your time here—chances are, you won’t even be considered seriously. They show clear partiality in hiring, which is unfair to skilled candidates from other states.
To make things worse, I asked for feedback, but HR (Carmila & Veena C S & Supriya M) simply said "we cannot share the feedback." So, not only is the hiring process biased, but there’s also zero transparency.
Even after Seethu Maria Johnson told me HR would contact me, they just ignored my performance and rejected me without reason.
Final Thought
Zoho might be a good company for Tamil people, but for others, it’s just disappointing and unfair. If you’re from another state, don’t waste your time here—your performance won’t matter, only your region and language will.
