Senior consultant Interview Questions

There are two main answers to this question. Initially spark partitions data via the Hadoop input format when reading from its source. Subsequently, it partitions data according to the level of parellisim such that a single task can process that data. This level of parellisim can be over partition. The level of parellisim can be overridden by some functions on a per function basis.

I can attest that this is quite true. The company develops great products but it's disappointing how they treat their candidates that they themselves contacted - it speaks highly of the organisation's culture and values.

It's a question you'll be asked in almost every consulting firm, so have a think about the implications of this before answering yes. This was asked of me in every interview during the process, and remains the one question that was really drilled in.

This was financial cost system related so answers were around close of dates, accruals & reporting timeframes

It was a conversation based around how you would approach the situation - types of questions to establish and avenues for the client & consultant team to work on.
