Syngene International Limited Research Associate - Data Science interview questions

I went through the following rounds, initially after panel round 2 they said we will not be going ahead. Then the HR contacted me again stating oh there was some miscommunication can you please take another round with the data science director. When I joined this round, the director did not join. Later the HR ghosted me for weeks and contacted me again but I did not go ahead. Round 1 - Telephonic with Hiring manager Round 2 - Panel round 1 Round 3 - Telephonic with HR Round 4 - Panel round 2 Round 5 - Round with Data science Director
