MediaTek interview questions and experience

Here are some MediaTek interview questions and experiences which had been will be shared. Refer to these interview questions and experience words prepare accordingly.

As we all know MediaTek is a fabless semiconductor hardware company. The company provides or produces the processor IC chips for wireless communication. Most of the time the company hires communication stream aspirants, but it also prefers VLSI specialization aspirants as it works on semiconductor hardware physical design.

The company MediaTek conducted the test through cocubes online exam.

The online test included around 49 objective questions and was given a time limit of 65 minutes. Solving the online test very fast was a must need. The online test had a total of four sections which are

Aptitude (Ten questions)
C (Ten questions, most of them were based on pointers)
Basic Electronics (Fourteen questions)
Optional based on profile Software or Hardware

MediaTek aptitude questions:

The aptitude section was moderate level. The topics which were included in the aptitude section were Number series, Data sufficiency, logical reasoning (Matching of images), paragraph based, and a question in which three connected gears which are rotated three times in the clockwise direction…, the number on the arrow of each gear will be?.
