1 Day - 4 Rounds

Round 1 - Technical : A friendly guy with medium seniority conducts first round. Asks basics of React, Redux, JS and Java (optional on Java; only if you are comfortable)

Round 2 - Technical (manager) : No offense, but a less technically sound person pretends he/she knows everything about React JS. You explain "Why React?" in depth ( till reconciliation) and yet he/she is still not happy, just because you didn't tell the formal definition. Overall not open to understand and accept that there can be multiple ways/perspectives to explain a single thing.

Round 3 - Technical (line manager) : You are asked about past and current projects, a few random technical things to judge your thinking ability. Intimidates you a little by confusing you with twisting the questions. Overall okay round.

Round 4 - HR Salary discussion. Bad experience. You will be asked your expectations; and told congratulations you have passed all the rounds, I'll send your expectations for approval and get back to you for documents in the next few days.

And you don't get a call, neither a reply to your mail. After 6 months they reply to you, "You were not found technically fit by the panel". (In reality it is more like," you were more than a good fit; but we don't have the budget")

UBS seems to be a good company, but seems to have hired wrong people for managerial positions (easy there, just my opinion based on my observation),

Advice/Suggestion to Talent Acquisition try a good staffing agency maybe; might help you to understand the market value of a candidate based on his/her skills and experience.

Explain the React component life cycle.
