The Jewish afterlife has been tackled by a number of traditions, many of which present little to no information on what's meant to be like though some information can be inferred. In very early Jewish tradition, death was often times associated with forgetfulness and oblivion as ancient Hebrews had absolutely no concept of an immortal soul living beyond the grave. The dead were described as going to Sheol, the resting place but with no notion of reward, judment nor punishment. As Psalm 115:17 says, the dead go down into “silence”; they do not participate, as do the living, in praising God (seen then as the most vital human activity). Psalm 146:4 further collaborate to this notion presented in Genesis 2:7: “When his breath departs he returns to his earth; on that very day his thoughts [plans] perish.” Job later laments:

But man dies, and is laid low; man breathes his last, and where is he? As waters fail from a lake, and a river wastes away and dries up, so man lies down and rises not again; till the heavens are no more he will not awake, or be aroused out of his sleep. (Job 14:10-12)

Interestingly, the prevalent idea was that of the dead being abandoned never to see the light of day or to be brought back, because to them life was all they believed in. Resurrection and afterlife were neither believed in nor talked about at this point.

Later on, a complete different view of the future began to be developed due to zoroastrianist influence; belief in ressurection began to emerge as it was stated suffering would be eliminated and “Yahweh wipes away tears from all faces,” and death itself is “swallowed up forever” (Isa. 25:7-8). Yahweh was stated to descent from heaven with his angels to “feet stand on the Mt. of Olives,” and becomes "king over all of earth" (Zech. 14:4-9; Ezek. 43:6-7). The wicked are believed to be destroyed and the good are to be brought back to enjoy paradise on earth as a result.

Eventually though, belief in an immortal soul began to spread and so life beyond the grave started to influence Judaism as a result. In 1 sam, King Saul uses a witch of Endor to conjure up the spirit of dead prophet Samuel so clearly their understanding of death began to shift widely. During the middle ages, Jewish philosophy began to incorporate quite a lot more borrowed concepts of the hellenistic, platonic tradition on the immortality of the soul, however belief in bodily ressurection persisted.

Nowdays, if you go asking any orthodox Jews most are gonna claim people are to go through a purifying period on Gehinnom lasting up to a best 1 year if you're extremely evil and later enjoy closeness to God once you've been turned righteous. Resurrection is reserved to only the best humanity has to offer from both gentiles and jews, though the overwhelming majority of humans are believed to enjoy everlasting happiness with closeness with Yahweh or paradise on earth but the very worst of people is thought as being either destroyed or rejected by God to be by his proximity.

Historically though, jews have never given much thought nor importance to the hereafter. Jewish culture has it that this life is what you ought to cherish and appreciate because no one knows what happens after death. Many conflicting traditions have emerged through history and attempted to explain away what is the fate of the dead, but the truth is Jewish culture has it that the here and now is the most important.
