  • Set the job priority for each query to Batch and expect to see query results within 24 hours.

Explanation: BigQuery offers a choice of two pricing models for runnig queries: on-demand (you are charged for the number of bytes processes by each query) and flat-rate (you purchase slots - dedicated processing capacity). If the exploratory queries are one-off, running in Interactive mode using on-demand pricing seems to be the optimal answer.
