Hey there,
Congrats on passing the first round!
95% of partner rounds are just as standardized as the first round. The reason why you read about freestyle partner experiences is that they deviate from what people expect, hence they post about it more frequently online, hence giving others the impression it is much more common.
Additionally, partner rounds are often perceived as more challenging, just because it's a partner sitting across the table rather than a more junior colleague. It is purely based on the impression and not on the content. :-)
If there are any deviations from the standard interview, expect them to be in the following realm:
- Focus on one or two areas where you were perceived as not as strong in round one, which can be specific case questions or fit stories
- Only doing a case, only doing fit instead of both
- Doing two shorter cases in quick succession
- Challenging your answers more
- Not providing any time for you to think about the answer, making it more conversational
In any case, the most important thing is not to be startled by this and just keep working on the case or the fit in a calm manner.
All the best for your second round!
Cheers,
Florian
