Interviewer was toooooo rude and after waiting for over 6hours to get the 1st round call, that fellow has finished in 10-15mins by asking irrelevant and illogical questions. He boasted that he has 20 years of experience however while walking to the interview room, he had a discussion with another his colleague where all the interviewees are going/coming to the panel rooms, those fellows were saying Reject everyone and wind up.. Which shows their pure arrogance and negligible attitude

One of the features on our cameras is a region-based motion search. When users view the camera, they can select a region to search for motion. The UI displays thumbnails where motion occurred in that region. We’ve created a server that can execute a motion search (the API has been simplified, but it is using live data!). The motion search will run on our office camera that is looking out at the street. Create an Android or iOS app that lets a user execute a motion search as follows: Create a view that shows the search region. Allow the user to select a subregion. A subregion consists of one or more Cells in a 10x10 grid that covers the full region. All cells are the same size. The top-left Cell is [0, 0], the Cell below it is [0, 1], and the bottom-right Cell is [9, 9]. Execute a motion search for the user’s selected cell(s) by making an HTTP request to: POST /ios/search HTTP request body is a JSON dictionary (don’t forget to set the content type header) containing: motionZones: Cell[] startTimeSec: Number (seconds in UTC) endTimeSec: Number (seconds in UTC) Use one hour ago for startTimeSec and the current time for endTimeSec. HTTP response body is a JSON dictionary containing: motionAt: Result[] where a Result is an array containing two elements: [ timestamp, duration of motion in seconds ] Note that this is live data. Feel free to change the start and end time if no motion occurred recently! Allow the user to execute a motion search and display a list of times where motion occurred. Format the display of the returned times in a human-friendly way =) What we’re looking for Submit a .zip file containing a working project. For iOS, this should be an Xcode project. For Android, this should be an Android Studio project. Share the file using Google Drive or Dropbox if it is too large to email. We’ll be looking at: Correctness - does it allow the user to execute a motion search? Polish - the design can be spartanly simple (you’re not being hired as a designer!), but it should be easy to use and not feel broken. We do greatly appreciate clean design!
