Interview
The first round at Econ Systems mainly focuses on aptitude, logical reasoning, and core technical knowledge. For software and embedded roles, questions are asked from C programming basics like pointers, syntax, and simple problem-solving. For electronics-oriented roles, the test covers circuit fundamentals, components, and sensor concepts. The reasoning and puzzle section is a bit tricky due to time pressure, but overall the questions are clear and well-structured.
