Amdocs UI Frontend Developer Interview Questions, Process, and Tips for Experienced

Interview preparation tips for other job seekers - 1) DON'T hurry/haste towards the answer. Take a pause, breathe comfortably. Revert back with some clarification on the questions. It helps in many ways. First it clarifies some of your doubts regarding some edge cases that might come up in the problem. Second, it buys time for you to get the solution. Third by asking questions, the interview will understand that you are very good at fetching the parameters of a problem statement which is a huge thing. You can say it's problem half solved.
2) Be confident in what you say. Important: If you don't know something (even if how simple it might be when you learn about it later), say you don't know. Period. Interviewers appreciate honesty. Don't beat about the bush.
3) TALK to yourself LOUDLY on the mike while solving question. It not only gives you more focus while solving but also gives the opportunity to the interviewer to understand your thought process in problem solving which is one of the key things that the interviewer looks for in an interviewee.
3) PRACTICE coding every single day for atleast half an hour. I would suggest Hackerrank is the best right now in the market. It even comes with "Interview Preparation Kit". Take that challenge. PRACTICE should inculcate TWO things. FIRST, Problems related to your language of choice.
SECOND, problems unrelated to any language. Basically
i) Data structures
ii) Algorithms
