ZF Group Graduate Software Engineer Interview Questions
& Process

the company is good but the exam is more important than the interview, the exam is moderate but the time will be less for it. I cleared the exam and the interview also went great but couldn't clear, they didn't tell any reason.

So, the first stage was this technical aptitude test, like they tested basic electronics, logical reasoning, and embedded programming. For logical reasoning it was stuff like percentages, profit/loss, directions, relations. Electronics covered diodes, logic gates, basic KVL/KCL, MOSFETs - pretty standard if you know the course well. Embedded programming was about memory types, communication protocols, code formatting, operator precedence, and graph tracing. Honestly, you could do okay even if you're not super strong in programming, as most questions were algorithmic, and about 4-5 were just about figuring out results based on operator precedence. There were about 180 students for this test, and 40 of us made it to the interviews. We had two offline interview rounds: one technical and one HR. The technical round also had a managerial flavor to it. The interviewers were really nice and welcoming, they introduced themselves and explained their roles. Interviews were mostly of two types: one for folks with technical projects (like me), where they asked about my work and favorite project, going deep into it. For those without projects or internships, they asked general electronics questions like RC/RL/RLC circuit graphs, ADC/DAC, SRAM/DRAM, MCUs/MPUs, op-amps, transistors, voltage regulators, and motors. Everyone got programming questions, and they accepted algorithmic answers. From those 40, 19 were selected for the HR round. HR started with the usual 'why ZF', future plans, location preference (Hyderabad), 'tell us your journey from childhood', and then some workplace scenarios. Finally, 11 people got an offer.

For the interview they asked questions mainly focusing on the resume. Since in my resume most of the things written were technical based, such questions were asked. All the questions were basic ECE questions, which were asked mainly to understand the level of basic knowledge you have.
