I applied mq spectrum through my college (Chennai) . The rounds include 1. Online Coding Challenge, 2. General Hr, and 3. Technical Hr via Web interview. The online coding challenge includes 10 questions and you have to solve all those under the time limit. Internet source is available for reference. We attended the online test using kattis platform. After clearing the first round you'll be into for General Hr. Just general questions to determine what's your presence of mind be like. Speak loud and clear, alongside don't give 2 or 3 answers. After I got cleared for the second round. An employee from Singapore (that's where the company hq is) did a web interview asking me to explain one of the codes. Just explain it nice and clear. Don't overcomplicate It. After clearing those rounds and that's it you're done.

First round was coding round. We can use any launguages(C, C++,java,python etc...) . There were 12 questions. After answering each question you score will be shown in leader board. It is an open source medium you can also refer google.
