One of my friends graduated from NIT Trichy and here are some facts about the institute I got to know from her.

As you have not mentioned any specifications, let me just describe the placement scenario of Metallurgy at NIT Trichy.

• The placements generally vary from year to year. 
• Out of a batch of around 60 students, people looking for placements every year is around 40.
• The rest of the people either go for higher studies or have some other plans. 
• Most of the people get into material science-related fields at very good universities.
• Out of the 40 students, around 30 usually get placed. 
• Companies that usually open for metallurgy graduates include, Core Metal (steel/ aluminium), Automobile, Analytics, Software and others.
• There are a few companies that are regular visitors. The rest depends on the market and your training placement coordinator.
• Placements for metallurgy students are lesser than the other departments.

So, you need to act upon those selected shots you get. You'll have many chances throughout the year. You will also get a lot of guidance from immediate seniors.
