Candidatei-me por meio de recrutador(a). O processo levou 4 semanas. Fui entrevistado pela Meta (Boston, MA) em mar. de 2018
Entrevista
I was contacted by HR on LinkedIn. After brief phone screen with HR ( was asked one Stats and a code question) I got scheduled for Technical Phone Screen. Though I was provided preparation material that said programming questions will be based on Pandas and Numpy, I was surprised when I was asked to write a program for tax calculations. I was able to write the logic right after struggling in the beginning but I guess it was too late. Probably would have done better if instructions would have not been misleading about what will be asked in the interview.

Pergunta 1
Write a program in Python to calculate tax if Salary and Tax Brackets are given as list in the form [ [10000, .3],[20000, .2], [30000, .1], [None, .1]]. You don’t know in the beginning how many tax brackets are there. You have to test for all of them.

Entrevista
1. Behavioral questions from recruiter around experience and check interests (30min); they will share interview preparation guide after this step if move forward
2. First round interview with ML/stats questions + coding/algorithm + data manipulation (1hr-if pass, there will be final round)
Perguntas de entrevista [1]
Pergunta 1
Data manipulation with language of choice (SQL/python): easy joining/group by questions
Coding/algorithm: easy level Leet code, be ready to discuss time/space complexity
Stats/ML: regression deeper dive
Took around 1 hour and has three parts, each of 20 minutes: SQL, coding, statsitics. At the end had a few minutes left and the candidate can ask the interviewer questions.

Entrevista
A Shared Coderpad of SQL, Python Coding, Stats and ML. The questions were actually pretty basic but the interviewer frequently asked nitpicky questions that a DS practitioner would never really think about (like what are the formulas for pooled variance). See questions below as examples.
(SQL) Given a table, provide all the pairwise combinations of IDs, without any duplicates. So with record1: ID1 ID2; record2: ID2 ID1; record1 or record2 needs to be removed.
