IIT Delhi typically offers internships to students in undergraduate or graduate programs. The application process generally includes the following steps:

• Check the internship opportunities available on the IIT Delhi website.
• Submit an online application, including your resume and a cover letter.
• Complete any additional requirements, such as taking a test or providing transcripts.
• Wait for a response from the internship coordinator or supervisor.

It's always a good idea to check the official website of IIT Delhi for the most up-to-date information on internships and the application process. 

IIT Delhi usually starts accepting applications around Jan-Feb. You are required to upload your Resume, Cover letter, and an overview of a Research Paper published by any faculty member of the department you are applying at. In case they consider you eligible for the internship they will contact you via your email. A good CGPA might help but is not necessary for an internship.

Department change is a very common debate among IITians so let me state some important points regarding the same to answer your question in a better way.

• Department change happens after the end of the first year during which students of every branch study similar courses
• The change is based on your CGPA and category 
• On an estimated 50 students from the General Category and 15 from the reserved category are allowed to change their departments
• CGPA should be above 8 to be eligible for branch change

Now if we roughly calculate 6-7 students from a textile branch out of 55 are eligible for branch change. The competition seems to be tough and you are required to maintain a certain CGPA to target a certain branch. The CG required to transfer to the following branches are

• CS: 9.6
• Metallurgy: 9.6
• EE: 9.4
• Mechanical: 8.8
• Chemistry: 8.4

If you are confident that you can achieve the required CG with the given competition, you can take them risk. But hear me out, even if you don’t manage to do so, remember branches can be switched in MTech too. Moreover, doing BTech from IIT Delhi will only open more opportunities and won't become a disappointment.

Here are some helpful tips for students starting their first year at IIT Delhi

• Try to work harder than the bare minimum and don’t limit yourself to specific tasks only
• Attend your classes regularly. This will help you prepare for your exams with minimal effort.
• Maintain your CGPA well despite your seniors' advice that CG does not matter. In reality, it does matter especially to secure good roles and packages. Moreover, foreign universities consider your CG when selecting for higher education
• Alongside your academics, make sure you pursue your hobby or anything that gives you a break from your studies
• Explore every nook and corner of your college and interact with almost everybody. Avail of every opportunity that comes your way.
• Don’t adopt a sheep mentality and follow every trend that your seniors have been following. For example, people tend to choose to code even if they are not interested just because it fetches good placements. 
• Whenever you feel you are at your lowest, share your concerns with someone, and don’t just keep bottling things inside.
• Have a balanced diet and try to hit the gym
• Stay away from distractions and bad habits
• Interact with people with different personalities and mindsets to broaden your network

All these pointers will help you shape your future and make you a better person.

IIT Delhi and BITS Pilani are two highly reputed institutions for engineering studies in India. I am a second year B.Tech Electrical student at IIT Delhi. During my time, I was faced with a similar dilemma. But I ended up choosing IIT Delhi over BITS Pilani for my studies.

I would recommend you choose Electrical Engineering at IIT Delhi over CSE at BITS Pilani because of these reasons:

• Brand Value: IIT Delhi carries the prestigious “IIT'' tag  which holds more brand value than the “BITS Pilani'' tag. This will become important to you when applying to foreign universities for your higher education. 
• Fees: As a government institution, the fees of IIT Delhi is much more affordable as compared to BITS Pilani. This in turn, gives IIT Delhi a higher position in ROI (Return on Investment) because it offers even better placements. 

Here are the important comparisons between Electrical Engineering at IIT Delhi and CSE at BITS Pilani:

*This is the fee-structure for General/OBC students with family income>5 LPA. Thus, I would suggest you choose Electrical Engineering at IIT Delhi over CSE at BITS Pilani.
