Sneiderman's charges are in relation to the investigation of the November 2010 murder of her husband, Rusty.
She was found guilty on four counts of perjury, three counts of making a false statement, one count of hindering the apprehension of a criminal, and one count of concealment of material facts.
She was found not guilty one count of making a false statement and three counts of perjury.
Sneiderman showed no reaction when the verdict was read.
"The state, they just did a better job in my opinion, as far as putting out all the evidence and hammering it home," said a juror who did not want to be named.
Prosecutors said Sneiderman lied to cover up an extramarital affair with her boss, Hemy Neuman. Neuman is serving life in prison for the murder.
"When she was a witness at the Hemy Neuman trial, we saw things where she said 'yeah, I'm not going to lie I can't hide feelings for him, I care about him,' things like that. It wasn't as one sided," said the juror.
The juror said testimony indicated Sneiderman did not fend off Neuman's romantic advances.
"In a situation like that, you can easily close the door on the guy and tell him leave me alone, stop messing with me," the juror told reporters. "It felt like a cover up in my opinion."
Defense attorneys argued that Sneiderman assisted police and that any delays in finding the killer were the fault of Dunwoody detectives, who failed to ask Sneiderman the right questions.
A sheriff's deputy escorted Sneiderman out of the courtroom and she was booked into the DeKalb County jail.
A gag order remains in effect in the case so neither the prosecution nor the defense had any comment after the verdict.
Sneiderman will be sentenced at 9 a.m. Tuesday.
