What do these terms mean:• Java, JavaScript?

• Front-end, back-end, full stack?

• Open source?

• What do these roles do?– Developer, Data Scientist, QA Engineer, DevOps,

Network Admin?7

Quality Assurance Jobs are Going Away

• Typically, Developers now test their own code

• Google has eliminated the role

• Largest companies that still have QA roles:

10

Types of Tech Terms - Examples• Concepts (MVC; RDBMS)• Programming languages (JavaScript, PHP, Go…)• Libraries (= ready-to-run pre-built code)• Environments, or frameworks (Visual Studio)• Methodologies (Agile)• Version Control Systems

• Understanding relationships between technical terms (at a high level) helps to write outgoing messages and talk with candidates

Sourcing Methods and Sites

21

Boolean Search Basics

While Boolean logic remains the same, Boolean search operators vary depending on the platform

22

LinkedIn Advanced People Search

23

Boolean Syntax• AND - must be capitalized. Using the AND operator is optional;

by default, LinkedIn will combine search terms

• OR - must be capitalized

• NOT - must be capitalized

• Quotation Marks

– "" - use the quotation marks to search for phrases

• Parentheses

– () – use the parentheses around parts of complex queries, to specify how to execute a search

24

Order of Operators

• The order of precedence for these search operators on LinkedIn is as follows:– Quotes [“”]– Parentheses [( )]– NOT– AND– OR

25

Vary Job Titles in a Faceted Search –LinkedIn.com• Example:("software engineer" OR lead OR developer OR MTS OR "technical staff" OR coder OR programmer) (NOT manager) (NOT QA)

• LinkedIn limits the number of ORs, ANDs, and NOTs you can use –shows no results if we use “too many” – but we have a workaround 😉

• Use the Job Title field, not Keywords 26

Use the Job Title, Not Keywords Due to the (questionable) semantic search interpretation, Keyword searches may return the wrong results

27

Vary Job Titles in a Faceted Search –LinkedIn Recruiter

• Current job title = ("software engineer" OR lead OR developer OR MTS OR "technical staff" OR coder OR programmer) (NOT manager) (NOT QA)

• Do NOT use predefined selections in Job Titles28

LinkedIn - Search Using Boolean in Job Titles (vs. Selections) in Recruiter• Recruiter interprets

predefined job titles and some results may be “off” (and some – not included)

• Use Boolean (vs. selections), with long OR statements if necessary

29

LinkedIn.com Boolean

Limitations

30

Workaround for AND on

LinkedIn• Just don’t use AND explicitly• Java AND spring AND rest AND aws AND nosql

AND "elastic search" AND microservices doesn’t work, but

• Java spring rest aws nosql "elastic search" microservices - does

31

Workaround for OR on LinkedIn1. Create an OR search string

• Mary OR Louise OR Joanna

2. Wrap all but the first term in ()s• Mary OR(Louise) OR(Joanna)

3. NB: remove the spaces between OR and (• Always Mary OR(Louise)• Never Mary OR (Louise)

4. Done32

OR Workaround• This search Mary OR Emma OR Sophia OR Linda OR Olivia OR Emily OR Victoria OR Lisa OR Isabella doesn’t work, but this does: Mary OR(Emma) OR(Sophia) OR(Linda) OR(Olivia) OR(Emily) OR(Victoria) OR(Lisa) OR(Isabella)

33

Workaround for NOT on

LinkedIn• The following NOT search engineer NOT senior NOT manager NOT director NOT recruiter NOT cto NOT ceoresults in error but engineer NOT(senior) NOT(manager) NOT(director) NOT(recruiter) NOT(cto) NOT(ceo)does work

34

Indirect (or Implicit) Search

Example: for technical candidates who may have a security clearance (and who did not mention the clearance on their profiles), search for target employers

35

Indirect Search Example• Search for Diversity

by looking for Historically Black Colleges

• Find the list of colleges by Googling

36

LinkedIn Search for Graduates of Historically Black College Grads

37

Tip Sheet:Google Advanced Search Operators• "" (quotation marks): look for an exact word or phrase• * (asterisk): wildcard for one or more words• filetype: Find only files of given types (such as MS Word or Excel)• intitle: keyword or phrase appears in the title of the result (blue line of

search results)• inurl: keyword or phrase appears in the URL of the result (green line of

search results)• site: get results from certain sites or domains (also called X-Ray)

38

Quotation Marks• Without "" around a single word, Google will

automatically look for the word variations and synonyms

• Use ""– around a word ("manager") to search for the

exact word

– around several words ("nosql database") to search for a phrase

39

* (asterisk) –wildcard within a phrase

On Google, * inside a phrase stands in for one or more words

40

filetype: - find specific kinds of files

Results must be a specific type of file (e.g., PDF, XLSX, DOC, etc.)

– filetype:PDF– filetype:XLSX

41

intitle: - find terms in page titles

intitle:"our team" "ex-Googler"

42

Resumes on the Open Web• Often simply searching for

intitle:resume <location keywords> <professional keywords> would bring up some resumes

• Add an area code or “gmail.com” to see more resumes and fewer false positives such as resume samples and job posts

• intitle:resume java back-end elasticsearch "gmail.com" san francisco

43

Looking for Resumes with inurl:

aerospace consulting "mckinsey" inurl:resume "gmail.com" -sample

44

site: - search by domain• site: searches are sometimes referred to as "X-Ray"

searches

• Return results only from a given domain

• Target:– Top level domain -> site:org– Domain -> site:linkedin.com– Sub-domain -> site:members.iccaworld.com– Directory -> site:edu/pipermail

45

site: ("X-Ray") Search - Examplesite:github.com "report or block" "Washington, DC" java python

46

X-Ray LinkedIn Examplesite:linkedin.com/in OR site:linkedin.com/pub -pub.dir javascript engineer "greater new york"

47

What’s -pub.dir?• Public profiles start

with site:linkedin.com/in

• However, some profiles are still indexed at site:linkedin.com/pub

• -pub.dir excludes lists of people with the same name

48

X-Ray LinkedIn for Titles and Companies

• For members who have current jobs listed on their profiles, page titles include:– Current job title for the top position listed on the profile (i.e. if there are

several current jobs, this would be the top one)– Current company name for the top position listed on the profile

• site:linkedin.com/in OR site:linkedin.com/pub -pub.dir intitle:"chieffinancial officer" finds people with the title "Chief Financial Officer"

• site:linkedin.com/in OR site:linkedin.com/pub -pub.dirintitle:facebook finds people who work at Facebook

49

Operators before: and after:• New - previously only available via Tools/Date Range

• Example use - attendee list filetype:xlsx after:2018

• Note though that many web pages do not have identifiable dates and won’t be included in search results if a date range is set

50

Setting Location and Language in Google Search

There are no operators for locations and languages, but you can set either in the advanced search dialog

51

Note on Google’s Number of Results• The number of search results is (almost always) misleading

• Google never shows more than 300-500 clickable results• To see more results (especially, from each site), choose

“repeat the search with the included results” on the last page

52

53

Operators (Full List) Meaning

such as resumes. Just as software code, documents are stored in the code section

• Use Github operators:– extension: allows to search for files of given types– Use filename: to search for document names – (these are like Google’s filetype: and intitle:)

• Popular resume formats include JSON and TEX62

Use Github Operators to Find Resumes• extension:json

Github CSE (Custom Search Engine) -http://bit.ly/SourceOnGithub

Example search: Java scala germany

100

Schema Objects (for Use in CSEs)• Schema.org defines a standard set of types of "objects",

such as Person, Physician, Organization, Event, Job Posting, and Blog Posting

• Sites often include objects such as Person in public profile pages’ HTML code. Examples: – LinkedIn, Meetup, XING, Github, Bloomberg.com, ResearchGate,

Doximity.com

• Googlebot collects this information101

Setting a Custom Search Engineto X-Ray for Profiles

• Go to https://cse.google.com and create a CSE by selecting a site to X-Ray (for example, Github.com or LinkedIn.com)

• Control Panel allows to set the type of Object, to which the search will be narrowed– (Google.com doesn’t have that option)

• Searching for the Person object while X-Raying a site usually narrows results to profiles

102

Examples Using Objects

• CSE: LinkedIn/Person example search: vpmanufacturing

• CSE: LinkedIn/JobPosting example search: vpmanufacturing

• CSE: LinkedIn/BlogPost example search: 3d printing

103

Advanced CSE Search Operators

• These are not available in Google but are in Google Custom Search Engines, allowing us to search precisely for some filters

• The filters and syntax depend on the site

• For X-Raying Github, the operators are:more:p:person-homelocation:<location> more:p:code-programminglanguage:<language>

104
