There is no clear advancement path within the company, mostly due to it being a small group and advancement is handled on an as-needed / skill-set available basis. If you have the chops to lead a team, you probably will - some random point in the future that won't be clearly indicated.
Reviews... There simply aren't any and this is probably because a review indicates that you, as an employee, are moving in a direction and, well, you probably aren't.
The work load for the company seems very feast or famine, making the work environment of iBeta very manic/depressive - if the sales team is on the ball, there's lots to do and the whole place is energetic. If the sales team isn't on the ball, layoffs are incoming and there's a constant wonder of when the axe will fall making the place very doom and gloom... And this can happen a couple times a month.
