Nettur Technical Training Foundation (NTTF) does not have an AICTE approval yet which is needed for your degree to be recognized as valid by other institutions in the country. If you are planning to do higher studies after the diploma from NTTF, then you may not get opportunities as it is not recognized. There is no point in doing a degree that is not recognized.

However, if you are looking for just a job after the course and nothing else, then it is good. It has good placement records and you will get ample opportunities for the same. I would say think twice before coming to this college if you are still not sure whether you are doing this course for just a job or higher studies.

My brother goes to NIT Calicut so I can give you some insight into their M.Tech VLSI and EDT course. Here are the glimpses of the placement record for the year 2020.

• The placement percentage for the programs MTech Microelectronics and VLSI Design has been 100%. All the 12 registered students got placed.
• The placement percentage for the program MTech Electronics Design Technology has been 71.4%. 10 out of 14 registered candidates got placed.

The average CTC offered to both of these programs is almost similar. Also, the course has a good ROI. M.Tech Microelectronics and VLSI Design is in great demand and it is turning out to be one of the best courses at NIT Calicut.

A friend of mine did her BTech from IEM Kolkata and now she is working as a Cyber Security Analyst in a big firm. Here are a few things that she experienced in her duration at the college. 

• Unnecessary Rules: Students often complain about the unnecessary discipline enforced by the college to attend all of the lectures and seminars irrespective of their choice and usefulness.
• Faculty: In terms of faculty, there is a mix of average and good professors. But most of the good professors are moving to different colleges. 
• Placements: In the terms of placement, the data may show it as amazing but in reality, most of the students of IEM end up in mass recruiting jobs offered by any IT company. Only a few of the students end up in good companies. 

If you are choosing IEM try to make the most of it. Other than college learning, try and take up some extra courses such as coding or hacking and security, it will help a lot. There are a handful of helpful faculties at IEM. Interacting and working with those professors will help a lot in going good places.

Learn to utilize their time and learn new things. Learn something new and read as much as possible. If you are not happy with campus placements then you should look for off-campus placements as well.

The most important thing you should know is which course will prove to be better for your career, rather than which is the best overall. As some of my friends are from NITIE Mumbai, I can give you a bit of information about PGDIE and PGDIM.

• Both PGDIE and PGDIM are flagship courses of NITIE.
• PGDIM is considered to be a management course, whereas PGDIE is a technical course.
• PGDIE is a more M.Tech equivalent.
• There are also certain differences between the course curriculum at PGDIE and PGDIM.
• PGDIE has a batch size of 120. And PGDIM has a batch size of 250.
• Admissions for PGDIE are done through GATE scores. For PGDIM, CAT scores are considered.
• The placements of both the courses are good. Students of both these courses sit for placements by almost the same companies.

Therefore, it is suggested that you opt for the one that suits you the best. Ask yourself where your passion lies and will a management course or a technical course be beneficial for you.
