Amazon BI Engineer Interview - Executive Metrics | Business Case + SQL

[@SwatiTirthramGulia]

Thank you, Dan, for consistently providing us with valuable and practical content

[@helovesdata8483]

I'm interviewing for BIE roles now and this is very helpful in general.

[@chaosstudios4330]

Don't know why metrics would be a ambiguous analytics problem cause leadership will always have priorities as part of business goals so they are aware of what metrics they need to make decisions. I'd assume logically business intelligence would need to show those specific metrics as requested and then perhaps an analysis of various areas of the business as a guidance for leadership to focus on. Giving random unsolicited reports and metrics makes no sense.

1 total trend - total # of customers - # total of transactions - total # of sales revenue 2 customers - # of customers based on the signup - 3 transactions - # of transactions over time - revenue of transactions over time - # of sales based on items - # of sales revenue based on items

This is exactly how a BIE interview at amazon is. The evaluation of response is spot on.

[@DataInterview]

Hey dan, interviewing for BIE role and they are mentionning « opportunity sizing » as part of the final interview. Can you help prepare for this?

[@donndonnn]

Hi Kevin, how did your interview go? Did you find out what they meant by that term?

[@MaxenceRonzié]

If I may, the data architecture with Customer & Transaction tables is not optimized at all. You should put a customer id in transaction table and remove the transaction id from the customer table because with this implementation the customer_id & sign_up_date are duplicated as many times as a customer made a transaction.

[@And_Nunes]

I thought the same thing

[@leassis91]

thanks for the content, Dan! Can you provide for us beginners the SQL solution?

[@djjiang3718]

Thank you Sir! Great stuff!

[@sandrahu7122]

this guy who answered the question either didn't have experience or doesn't have business acumen. he didn't get the thing right, the executives only want to see the big picture of the transactions, not the details. as an analyst, you need to know who is your audience. he is talking no sense around

[@tysong9883]

are you sure the last line "limit 100" will correctly give top 100 VIP customer? Actually it's customer/date level data.

[@TyTyBoro]

Very helpful!! Thank you!!

[@baderalhousainy]

Thank you guys for this interview. wondering about two things. dose amazon use power bi or tableau? also, why would he need to write the query if this Dax is almost ready if he could load the data from the server to the dashboard?

[@kunalrath5352]

SELECT AVG(items) AS average_order_size FROM Customer AS c JOIN Transaction AS t ON c.transaction_id = t.transaction_id; I optimized the SQL query. Can't we use this?

[@princebansal5483]

Very helpful video.

[@kanchidoshi6907]

Is it more relevant to Loop round or initial Technical screening?

[@Slamo28]

Super helpful

[@nareshvadlamudi]

Thanks Dan, very helpful. Just wondering in which level does this interview belong to - starting/Intermediary/Advanced level?

[@DataInterview]

Starting / Intermediate

[@tigerbear3038]

Hey Dan, how did you come up with this format for the Amazon BI Engineer interview? Was it based on actual BI Engineer interviews?

[@jonathanl7204]

Amazon interviews are structured like this. They usually do not ask you questions on metrics but 3 SQL questions immediately

[@GokulGourav]

@@jonathanl7204 what are those 3 questions?

[@donndonnn]

@@jonathanl7204 mind sharing what those questions are ?

[@laurab6180]

I excelled the SQL but couldn't ace the Python part

[@OjasBhanarkar]

Hey! Can you please share what exactly in Python were you asked?

[@vinayanayak1228]

hey , can you tell what questions were asked to you?

[@Rohit_Ankita]

Don't miss the explanation at the end.

[@DataInterview]

Agreed :)

[@BINTETA.42CAORIS]

Walk. Physical

[@baloney_sandwich]

U know this isn’t real because it violates Amazon confidentiality clause

[@sandrahu7122]

why is it so difficult for that person to answer the first question: metic-total sales, number of transactions, he is fxxking talking no sense for so long.
