Congregate and join both bring people together, with a difference in what and how. Congregate is for people to come together in a crowd, usually of their own accord. Join is to connect two things directly, or to become a member of a group. Congregate crowds people together; join links things or adds one member.
Both bring together, but one is a crowd forming and the other a single connection. Congregate, from Latin gregare 'to collect into a flock', describes people gathering into a crowd of their own accord — worshippers, protesters, birds. Join, from jungere 'to yoke', connects two things directly or adds a person to a group. People congregate in the square; a new member joins the club. One is a crowd gathering by itself; the other a single thing linked or added.
congregate
To congregate is for many people or animals to come together into a crowd in one place — usually of their own accord, and often for a shared purpose. From the Latin con- 'together' and grex, greg- 'flock' (the same root as gregarious and segregate). Students congregate in the courtyard; starlings congregate at dusk; protesters congregate in the square. It is intransitive — a crowd congregates on its own — and close to gather, but with a stronger sense of a mass assembling in one spot.
join
To join is to connect two things directly, or to become part of a group — join two pipes end to end, join a club, join hands. From the Latin iungere, 'to yoke'. At its simplest it makes one continuous thing out of two: where two roads meet, they can be joined into a single route. With people it means to enter or take up with — you join a team, join the queue, join forces. Unlike things that merge into one body, joined parts keep their own ends; they are linked, not dissolved.

Ask whether a crowd forms or one thing is linked. Congregate is people gathering into a crowd on their own — a square filling shoulder to shoulder. Join connects two things, or adds a member — a fresh link closing two chains into one. If people crowd together of their own accord, they congregate; if two things are connected or someone signs up, that is join.

Congregate is almost always people (or animals) crowding together spontaneously and intransitively; join is a direct connection or an individual becoming a member, and is transitive with a far wider range (join two wires, join a queue). A crowd congregates; a person joins it. One is a mass forming, the other a single link.
