I got mail from Tismo HR via naukri.com. I attended interview for role (Firmware engineer with 2+ year experience)on feb 8th 2020. Interview had 4 rounds. 1 Written Test(C programming) and 2 technical round and 1 Hr round. Reporting time was 9 AM. As soon as you enter, the security person will give you a form, you need fill your education details, current working company , current salary and variable pay also if any hikes in salary then date of the hike ect. Then you have to submit this sheet along with resume and photo to him. Then HR will process these and you'll be called for further rounds accordingly. Unfortunately I couldn't clear 1st technical round.

First phase was aptitude test contain 50% coding and 50%aptitude. Followed by 3 technical round interview and one HR interview. Technical interview mainly focused on writing code and asking projects related questions
