GE HealthCare Sr. Software Engineer interview questions

I got a call from consultancy that my profile has been shortlisted for F2F round (Whitefield, Bangalore). Interview date (15-Dec-2018) When I reached the venue (9 am), there were already 200+ candidates (different skill sets). I was called for my first technical round at 11:00 am. The interviewer asked me about my current project, company, few basic technical questions and coding. It lasted for around 20+ mins. Then I was told to wait outside for the next round. The situation outside was very chaotic as many people were waiting for their first round. I waited till 1 pm and then asked about the status. The HR told as there are many candidates and parallel interviews are going on, so its taking some time to get the status. One good thing they did was to provide lunch at the venue otherwise many people would have left during that time itself. At 2 PM, again I asked about my status. They told they will check and let me know. By this time many people already left because of all this. At 4 pm one guy came and wrote our names (people waiting for 1st round feedback) and left. At 5 pm again same guy came and wrote our names (to check the status). Finally at 6 PM he came and told "You can leave for the day" It was my worst interview experience. If a candidate has not cleared the first round, you can inform them then and there itself, why ask them to wait for 7 hours. (My first round was good that's why I was waiting and was told to wait for next round). Total waste of time, they should value other people's time (I came all the way from Jayanagar to Whitefield, 25km's one side) to attend the interview. Pathetic interview process. Good interview venue (Four points by Sheraton).

Two to three rounds will be there . The first round is telephonic or on the basics. The second one is more on the depth of the technology and the last round will be managerial. After all this will be the HR round that will be there.
