It is slowly becoming difficult to maintain due to so many rules but here it is:

ErrorDocument 403 /www.domain.com/error404.php
Options All -Indexes
RewriteEngine On
RewriteBase /

RewriteCond %{REQUEST_METHOD} POST [NC]
RewriteRule ^ - [L]

RewriteCond %{HTTP_REFERER} !^http://(www\.)?domain.*$ [NC] 
RewriteCond %{HTTPS} =on
RewriteRule ^(.*)$ http://%{HTTP_HOST}/$1 [L,R=301]

RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

# redirect /profile?eid=1 to /eid/1
RewriteCond %{THE_REQUEST} \s/+profile(?:\.php)?\?(eid)=(\d+)\s [NC]
RewriteRule ^ /%1/%2? [R=301,L]

# internally rewrite /eid/1 to /profile.php?eid=1
RewriteRule ^(eid)/(\d+)$ profile.php?$1=$2 [L,QSA,NC]

# redirect /dept?did=1 to /did/1
RewriteCond %{THE_REQUEST} \s/+dept(?:\.php)?\?(did)=(\d+)\s [NC]
RewriteRule ^ /%1/%2? [R=301,L]

RewriteRule ^ /%1/%2? [R=301,L]

# internally rewrite /job/1 to /job-details.php?job=1

RewriteCond %{THE_REQUEST} \s/+([^?]+)(?:.php)?\?do=([^&\s]+)&w=([^&\s]+)\s [NC]
