IIM Lucknow panelists test ECE engineers on fundamental concepts like differences between electrical and electronic devices, TV display technologies (LCD, OLED, CRT), and practical applications of electronics (washing machines, transmission systems). The OP of this thread was asked: difference between electrical devices and electronics, different types of display in TV, materials in cathode ray TVs, and how to measure Qutab Minar height using a pen and ruler. IIM Lucknow at Rs 22L fees and Rs 32.
3 LPA average evaluates engineering graduates on domain knowledge, problem-solving ability, and business relevance of engineering. Preparation for ECE engineers: revise core subjects (signal processing, digital electronics, communications, semiconductor devices), understand business applications (how TV industry works, telecom sector economics), and practice engineering estimation (Fermi problems). For the Qutab Minar question, the elegant answer is: hold the pen at arm's length, adjust until it covers the minar from bottom to top, note the angle of inclination, use trigonometry (tan angle = height of minar / distance from minar).
IIM L's panel at Taj Bengal Kolkata in 2026 had 2 panelists (1 friendly, 1 adversarial). Check your eligibility at collvera.
