ClusterDev Software Engineer Android interview questions

I saw the job posting on LinkedIn and applied through the link on their site. Then I received a call from the recruiter to setup a call with the interviewer. I had two rounds Round 1: I was asked to convert a javascript function to find distance (given the longitudes and latitudes) into kotlin and make it as simple as possible. Also how to find the n number of closest people to a certain long and lat. I was then asked about memory leaks in android and how to cause a memory leak. Then I was asked why an ANR is caused, how a memory leak causes ANR. Round 2: Implement a spacebar cursor feature as seen in Swiftkey. I was given a bare minimum keyboard codebase on top of which I had to implement this feature. After I finished the assignment there was a discussion/code review. I was asked to consider touch sensitivity. Then I was also asked about Handlers and why they are used in Android.
