Entire day that consisted of:
Presentation by HR and head engineers about the company
A group construction task followed by a Q&A
Individual Business task where you would have to derive from given figures given in order to find your solution, VERY, VERY difficult, followed by a Q&A
Typical generic Interview questions. NOTE: They would also ask questions on a topic you will not know, to see how your thought approach works- not hard if you're good at planning and thinking ahead while in the present.
Overall ~7 hours, lunch, teas & coffees provided.
