Mediaocean Sr. Software Engineer interview questions

My process started by being matched up with their internal recruiter. She managed to send an incorrect resume (not my resume) for the technical interview and got me interviewing for a position that they wouldn't be able to provide. The recruiter did get back to me later offering another related position before ghosting me after I replied. Total waste of time for me and their director of engineering (the tech interviewer) thanks to a terrible recruiter.

Interview process comprised of one telephonic technical discussion, aptitude test followed by 2 In Person Technical discussions, Product Director discussion and HR Discussion. All the rounds were conducted on the same day itself and interview process is also pretty quick.
