Interview Preparation Tips

Round: Resume Shortlist
Experience: Resume based shortlisting initially.

Round: Interview
Experience: 3 rounds of interviews (15-20 minutes each)
 All topics were Metallurgy related
 Heat transfer, Phase diagrams (very basic Fe-C diagram), FEM-based technical questions, are concepts asked.
Tips: If they look interested in a particular aspect, pursue it, and drive the interview.
Be ready to be grilled on the things mentioned in your resume.
 For consulting companies alone (McKinsey and BCG), look at certain case studies. The book "Case in point", is a really good source.
 For most other core companies (like Reliance, Tata Steel, etc.), refreshing Iron and steel and Mechanical Metallurgy courses will help a lot.
