Terrible experience. No consideration to have the courtesy to tell me the outcome, despite the fact I had spent a week on two presentations. Final feedback contradicted what they told me in the interview room.
Initial HR Phone call about my CV, this was fine and friendly enough.
1:1 with hiring manager, was relaxed and friendly
For final stage, it was a group panel and I had to prepare 2 presentations. This is a lot of work. I was therefore appalled that they didn't have the decency after 3 rounds of interviews to tell me I was unsuccessful. I chased for feedback twice, first time (after 3 weeks) HR said a decision was not made. After chasing again they told me I didn't get it.
I would not recommend working for a company that treats people like this at interview stage.
