TLDR; Go to bottom of post.

Around this time two years ago was the start of my group project in University. The project was to write an app in android and have a web side to it too. The group was to be overseen by a member of staff. The first meeting was introductions and to look at the spec, during the second we were to decide a group leader (PM) and other positions.
A person I shall call BD and I volunteered for PM. I didn't have experience with leadership but wanted some, and was the only one with confidence in android, the biggest part of the system. I got four of the votes.
BD, with his scouts experience, not being afraid to breathe down people's necks and bash some heads together, and having been PM last year, with his group receiving 69% (he failed the year and was resitting), earned 5. One guy was missing.
When it came to sorting out roles and responsibilities, BD confessed to not being a strong coder but that he'd help here and there. His role was planning our deadlines, doing our Gantt chart for deliverables, and was supposed to write a really detailed spec. He didn't have it at the meeting of the next week, as it was still in the works, and never messaged anyone. Next week he turned up with a Gantt chart of 1A4 page that only included the deadlines and deliverables in the spec, with three colours. One for android team, one for DB guy, and one for web team.
The guy who didn't turn up for voting got a girlfriend, a job at mcdonalds and did barely a thing. One guy in the web team did everything, carrying his friend who wouldn't do work (and also got swept out to see in a rubber boat with one of his bros lol (he was rescued)), and even though I'd done android dev I wasn't as quick a learner as two others in the team. Out of 10 people, 6 did real work.
The web guys stopped coming to meetings as they were taken over by android talk, and as we were quite behind, BG tried yellow carding them. They turned around with the website pretty much done, this one guy doing more than the 4 of us on android had. Yellow card lifted. We'd already complained about BD and his lack of everything (except screen brightness as he sat at the front of the lecture theatres with his wide brimmed hat looking at 9gag and videos (remembering he said he was resitting that year)) but grew a stronger dislike. Found out that he spent most of his time with his gf at our secretary/fellow android dev's house. Come coding week, he disappears entirely, only to attend meetings. He gave us a shell of the android code used for his previous year's project (along with documentation, complete with names and dates of updates, most of them (including the planning ones BD was supposed to do) bearing either one of two names. It was behind where we were at the time and had a lot of differences to our spec, and if we had used it BD may have used that to pull us down with him if things went wrong. He resurfaced at the end with the final documentation of how we'd all done, including reports on how each member had performed, which we were supposed to have reviewed. Our main, most proficient dev he accused of being irritable and brash, and a bad communicator. He was Norwegian, his voice was just a bit gruff, and he was driven and didn't waste time. He bashed the web team for not turning up, and had already been rude and unhelpful to everyone who voted for him in the first place.
In our own reports we all devoted paragraphs to delicately describing his contributions, excluding his suggestion that we use the code he gave us. Before we had our results and our work was completed, he individually kicked us from our group's facebook group and unfriended us.
Our 43% mark at the end, coupled with his -40% penalty from the red card we had him on, felt good, but not as good as a better result would have, especially as the fool that was BD would be inflicted on a group a third time. He changed to some other course after that year finished, so he must have failed his resit of second year.
During third year, a friend of mine who was PM for a group that passed well passed other things with too slim a margin to be happy, so chose to resit the year. He didn't have to do the group project again, and had that time free. But BD had to resit. His group had 69%. A yellow card with a 20% deduction wouldn't do it, so he MUST have had a red card as PM his previous year. Well that didn't come up when he claimed credit for his team's 69% during elections... My housemate's compsci boyfriend 2 years up overheard me talking about him, he was in 1st year with BD. BD failed and resat 1st year too. 4 years and he couldn't make anything stick. I feel bad for him through understanding the pains lack of work and internet distraction bring, and unfortunately I can't wish bad things on him because he brings them on himself. I wish I never see his face again though.

TLDR; Guy in group project lies and is dishonest from start to finish, getting PM pos by 1 vote. Gets what he earns.
