What is a data lake in basic terms?
Got messaged by a C3 . ai recruiter. Read that wlb is bad and that the interview process is absurdly long, but the Glassdoor reviews are 4.2 and can't find actual hours worked posted by anyone. How's the culture really? I'd be aiming for DS consulting, something more functional but with DS/ML concepts as my differentiator.

Wildly inaccurate. I just guess based on past experience. Then I write a bunch of caveats into the sow.

Here is the real method. Take your first guess and multiply by 6. Partner will demand it be cut in half at least and at that point you will be pretty close.
Planning fallacy says you are usually 2-3x off.
Finally don't assume you will be the one doing the work when estimating, consider the the experience level of the people that will actually do the work.
Sometimes experienced professionals will create an estimate based on their level of experience, negleting the level of experience of the people actually delivering the project or activity.
I think it is good to involve the senior staff when estimating work. You dont always want to get the opinion of an analyst when estimating work, but shoud get input from your circle of trust so to speak.

Based on historical. Get a sense of quality of data/how big of a pain the client will be - pad from 25-50%+
T&M because COs are always going to be necessary. Client will always want to add new data from lord knows where
For ETL - estimates were based on prior projects/experiences. Also always added 2/3 days of padding.
