Questions for your field
Your mentor asks what a first interviewer in your track would ask: about you, your college work and the basics of the field.
You answer like it is real
Camera on, resume open. Your mentor plays the interviewer and does not help you along.
Your assessment
In the last part of the call, your mentor tells you what went well, what to fix and how to answer better next time.
It is optional and separate from applying. Every internship includes one mock interview, and we email interns a link to pick a time. When your internship is over, placement agencies we work with can also help with your job search, paid separately.

Students from colleges like yours, in towns like yours.
Check any internship before you join
Fake internships are common. These four checks tell you if one is real.
- They never ask for money before you are selected, and never for a certificate.
- You speak to a real person before you start.
- Your acceptance letter names the company you will work with.
- Your certificate can be checked online.
We pass all four. Check us the same way.
Questions students ask
Is there any fee?
Applying is free. If you are selected, the internship fee is ₹2,999, paid in two parts: ₹750 when you join, and the other ₹2,249 at least 30 days before your internship ends. Your acceptance letter shows both before you pay anything. The fee includes one mock interview with a mentor. Fees are not refunded, so read your acceptance letter before you pay. There is no fee for the certificate, and the training for your track is free for interns. If anyone asks you for money before you are selected, or for a certificate, it is not us: do not pay, and tell us.
Is it paid?
Some roles pay a stipend. Paid roles are onsite, at the company's office, for selected candidates. If your role pays, the amount is in your acceptance letter before you start. If it does not, we tell you up front.
Will my college accept it?
Most colleges accept an internship that comes with an internship acceptance letter, a completion letter and a certificate that can be checked. We give all three, and an hours sheet if your college asks for one. Check your college's rules first. [REVIEW]
Who will I work with?
A team in one of our group companies. Your acceptance letter names the company before you start.
How does the mentor work?
Your mentor is someone from the team. They review what you submit every week, tell you what to fix and answer your questions. [REVIEW: how often]
How is the certificate checked?
Every certificate has an ID. Anyone can enter it at 3sintern.com/verify and see your name, track, dates and whether it is valid.
How long is it?
Internships run 1 to 3 months, depending on the track and the role. Your acceptance letter gives your exact dates.
Online or office?
It depends on the role: online from home or college, at our office, or a mix. We settle this with you when you are selected, and your acceptance letter says which. [REVIEW]
What if I am not selected?
We tell you, so you are not left waiting. You can take a training to build the skill, and apply again later.
Who can apply?
College students who are 18 or older, usually from the third year on. Any degree works: B.Tech, BCA, B.Sc, BBA, B.Com and others. [REVIEW: which years qualify]
When does the next batch start?
We start a batch when enough students in a track are ready. Your start date is in your acceptance letter.
Will this get me a job?
It gets you ready for one. You leave with real work to talk about in interviews, skills you can show and a certificate recruiters can check. Every internship also includes a mock interview with a mentor, so your first real interview is not your first try. When your internship is over, placement agencies we work with can help you find openings and apply, as a separate paid service: help with your job search. The job offer is up to you and the company that hires you, so be careful of any internship that promises one.
Do you help with placements?
Yes. Placement agencies we work with help you find job openings that fit your track, get your resume ready and apply. For our interns, this starts once the internship is over. It is optional and paid separately, and it has nothing to do with your selection or your certificate. See how the help with your job search works. To practise first, book a mock interview with a mentor for ₹299, whether or not you intern with us. The agency helps you apply. The job offer is between you and the company that hires you.
