AQR Capital Management Associate Software Engineer interview questions

Ghosted! I was contacted by the company HR directly for the job opportunity for Bengaluru office. The job was for a full stack role in their operations department and four rounds of deep techinical discussions happened with US based panel for about 1.5 hours each along with a two hour online assessment. Discussions were pretty positive but ultimately I didn't hear back and was ghosted. Ultimate waste of time.
