Auto-Sector Interview Preparation

DOHC (Dual Overhead Camshaft) has two camshafts per cylinder bank, allowing separate control of intake and exhaust valves, giving better performance and fuel efficiency. SOHC has one camshaft controlling both.

A turbocharger uses exhaust gas energy to spin a turbine, which drives a compressor that forces more air into the engine intake, allowing more fuel to be burned and increasing power output.

BEV (Battery Electric Vehicle) runs purely on electricity. HEV (Hybrid Electric Vehicle) uses both IC engine and electric motor but cannot be plugged in. PHEV (Plug-in Hybrid) can be charged externally and has a larger battery.

Regenerative braking converts kinetic energy back to electrical energy during deceleration. The electric motor acts as a generator, charging the battery instead of wasting energy as heat through conventional braking.

QA (Quality Assurance) is process-oriented — it prevents defects through process improvement. QC (Quality Control) is product-oriented — it detects and corrects defects in finished products.

FMEA (Failure Mode and Effects Analysis) is a systematic method to identify potential failure modes in a product or process, assess their effects and causes, and prioritize corrective actions.

Listen to concerns, understand the budget constraints, highlight value proposition, explore alternative models or financing options, never undermine the product value, and find a win-win solution.

Listen to customer complaint carefully, reproduce the issue, perform a visual inspection, use diagnostic tools (OBD scanner), check service history, identify root cause, recommend and carry out repair, verify fix, and deliver with job card.
