Motorola Solutions Java Software Developer interview questions

I was contacted by a headhunter through LinkedIn. I received an email from Motorola with a Codility challenge: one task was to return an array of integers which sum up to 0 given n (how many numbers), second was to debug a code by changing only three lines in it. There were 55 minutes for those two. Then I was invited for a 2h interview both technical and "tell me about yourself".
