• Phone call from recruiter on a weekend (Saturday).

• Hackerrank test next week.

• Four interviews scheduled approximately two weeks later:

  • System design
  • Spark pair programming
  • Pair programming and design
  • Hiring manager

Two of these interviews were scheduled late at night in Indian time, despite my availability during the day. I am concerned that the hiring manager, who had minimal data engineering experience and was eating breakfast throughout our conversation, made the final decision. This level of unprofessionalism from Coinbase is particularly striking, given their meticulous scrutiny of minor details, such as repeating a functional line of code as "unclean coding" during interviews.

• No feedback or update was provided after the rounds, indicating a lack of respect for candidates' time.

Edit:

I received a feedback call from the recruiter today, several days later. The reason for rejection was as I suspected: the hiring manager declined without providing further feedback or justification. It is clear that the company does not value the data engineering role or function. As it is a new initiative at Coinbase, it is likely a dead-end job for Data Engineers, offering no prospects for growth or appreciation from management who lack the necessary knowledge. It would be best to avoid this opportunity.

Why several switches in your previous roles?
