How candidates prepared

  • Pointer and output questions for the written test
  • Design and console-application practice; one candidate says practising LLD is essential

What stands out in these accounts

  • The same stages appear as in the Software Developer accounts: a written test, coding rounds and a console-application round.
  • One 2025 candidate had three coding rounds before a design round.
  • One experienced candidate (2+ years) lists the actual aptitude questions and a ZOBUS bus-booking application spec.

All about Zoho interviews

About these pages

Compiled by hand from 6 public first-hand accounts of Zoho interviews (2018–2025) on sites such as LeetCode Discuss, Medium and GeeksforGeeks. A question is listed only when a candidate stated it, in the round they said it came from; reposts of one account count once. Wording is the candidate’s. There are no answers here by design: the point is what was asked.
