Interview Preparation Tips

Round: Group Discussion
Experience: You are given the topic or asked to choose any topic of your own. They gave us 5 minutes to discuss among ourselves about the topic and 10 minutes for the actual GD.
My GD experience went well. My team somehow was bent on connecting 'going slow' to 'digital india' and 'tech in rural india', Our final topic chosen was "Impact of going slow in digitalisation of india" keeping a product in mind.
We tried to touch upon if going slow is beneficial or otherwise in the various processes of product development (ideation, creation, implementation). we discussed reasearch for new products to be a slow process while expansion of any new idea to be fast paced and in tune with competitors.
Tips: -All abstract topics mostly, so try to think beyond 'digital india' and 'tech in rural india'. Keep an open mind.
-Dont take the 5 minute discussion time lightly. They observe your leadership skills there. This is the chance where you bend the discussion to the direction you want to. And you are not even competing with each other...so bring in as many ideas as possible.
-Try to speak atleast once in the start,
-Let others also speak. Infact its a plus point if you let a person who hasnt spoken a chance 'in fair manner'.
-Avoid repeating the same idea too many times
-Conclude.
Duration: 10 minutes

Round: HR Interview
Tips: Choose the answer to 'what drives you' wisely. Any technical question will follow in the same field.
Keep the answer to "Tell about yourself" structured.

Round: Technical Interview
Experience: As my favourite subject i said digital system and coding. My internship dealt with solar energy, li-ion batteries, pcb designing.
Questions that followed were:
System-on chip?
As a design engineer, what are the parameters you think are required for a new age chipset?
