I've cleared 1st round , the round is based on java and C only, Be strong in basics and intermediate level of programming and concepts. However it'll be like a pen and paper round .

The Zoho software developer interview is a grueling marathon that prioritises raw logic and coding endurance over theoretical memorization [1, 3]. It typically kicks off with a high-pressure Written Test featuring C-programming snippets and aptitude puzzles, often in a fill-in-the-blank format to eliminate guessing [2]. The core of the process lies in two distinct coding stages: a Basic Programming Round involving 5–8 complex logic problems, followed by a legendary Advanced Design Round [1, 3]. In this "real test," you are tasked with building a fully functional system—like a Railway Reservation or Taxi Booking app—from scratch within 3 hours to demonstrate your mastery of Object-Oriented Programming (OOP) and system architecture [3, 4]. Finally, technical and HR interviews scrutinize your projects and cultural fit, often diving deep into your family background and personal motivations [1, 4].
