Tech track
Embedded Systems
Program and test hardware: microcontrollers, sensors and the code that runs on them.
Placement depends on what each team has open, so pick this track as your first or second choice in the form.
Apply for this trackWhat you will work on
Three tasks from the kind of work interns do in this track. Yours depend on the team you join.
Read a sensor and log the data
Wire up a sensor, write the firmware to read it, and log clean readings over serial or to a dashboard.
Write a test plan for a device
List what can go wrong with power, timing and inputs, then test each case and record the results.
Fix a timing or power bug
Use a logic analyser or debug prints to find why a device misbehaves, and fix it.
What your mentor checks
Your mentor is someone from the team. They review what you submit every week and ask questions like these. [REVIEW: how often]
- Did you read the datasheet before guessing?
- Does your test plan include the failure cases?
- Are your readings repeatable?
- Are your wiring and code written up for the next person?
Skills you will use
You do not need all of these on day one. The training for this track covers the basics, free if you are selected, and you learn the rest on the job.
- C for microcontrollers
- Arduino, ESP32 or STM32
- Reading datasheets
- UART, I2C and SPI
- Multimeter and logic analyser
- Test plans
A certificate anyone can check
When you finish, your certificate names this track and your dates. Recruiters can check it online with its ID.
Good to know
Mock interview
Practise with a mentor before your real interviews: 30 to 40 minutes online, then honest feedback. ₹299 on its own, and one is included with every internship. Expect questions like these.
- What is the difference between a microcontroller and a microprocessor?
- When would you use an interrupt instead of polling?
- How do I2C and SPI differ, and when would you pick each?
- Your board works on the bench but resets in the field. Where do you start?
When your internship is over, placement agencies we work with can help with your job search: openings in your field, your resume and applying. It is paid separately.
Questions about this track
Do I need my own hardware?
For office roles, the team gives you the kit. For online roles, you may need a basic board. We tell you before you start. [REVIEW]
Is this only for ECE students?
ECE and EEE students fit best, but computer science students who like hardware are welcome too.
Which degree fits?
B.Tech or B.E. in ECE, EEE, instrumentation or computer science. [REVIEW]
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.
What if this track has no open seats?
We talk about your second choice. If neither fits, you can take a training and apply again for the next batch.
